They still loved each other. They still wanted more time together. So why did Sakiko and Mitsuru choose to end their marriage?
The final episode of Until the T-Shirt Dries (T-shirt ga Kawaku made) delivers one of the most quietly devastating breakups in recent Japanese television.
There is no explosive confrontation. No final revelation that suddenly makes one partner unforgivable. No dramatic declaration that love has disappeared.
Instead, Sakiko and Mitsuru wash their laundry.
They hang shirts, sheets, pillowcases, cushions covers and curtains outside. They secretly spray water onto the fabric to prevent it from drying too quickly.
Neither wants their final moments together to end.
Yet they have already decided to separate.
For some viewers, the scene is heartbreaking and beautiful. For others, it makes the divorce even more frustrating.
A Reddit discussion about the finale captures the contradiction: if the two characters are so clearly attached to one another, why not simply remain married?
The answer lies in the difference between loving someone and feeling safe in a life built around them.
And the series makes that distinction far more uncomfortable than a conventional romance would.
Spoiler warning: This article discusses the complete ending of Until the T-Shirt Dries, including Episode 10.
The Short Answer: Why Did Sakiko and Mitsuru Divorce?
Sakiko and Mitsuru divorce because their marriage has become a source of anxiety rather than security.
Mitsuru is increasingly afraid of upsetting Sakiko. He becomes excessively careful, trying to avoid doing anything that might make her reject him.
Sakiko, meanwhile, lives with the fear that Mitsuru might disappear again.
Both are trying to protect the relationship.
But their efforts create a home in which neither can behave naturally.
The marriage continues to carry expectations of permanence and stability, yet neither partner feels able to trust that stability.
Their divorce is not a declaration that love has ended. It is an acknowledgment that their existing way of being married no longer works.
That distinction is central to understanding the finale.
The two do not necessarily want to remove each other from their lives.
They want to escape a form of togetherness that has become painful.
Whether divorce is the best solution is precisely what makes the ending controversial.
The Real Problem Was Never a Lack of Love
Romantic dramas often present love as the answer to a relationship’s problems.
If two people genuinely love each other, the expected ending is reconciliation.
Until the T-Shirt Dries challenges that expectation.
Sakiko and Mitsuru clearly retain affection for one another.
The finale does not ask viewers to doubt that affection.
Instead, it asks a harder question:
What happens when love itself becomes tangled with fear?
Mitsuru wants to avoid hurting Sakiko.
But the more carefully he behaves, the less spontaneous and honest their relationship becomes.
Sakiko wants to believe that Mitsuru will remain with her.
But his previous disappearances have made that belief difficult to sustain.
The result is a painful cycle.
Mitsuru tries harder to reassure her.
Sakiko becomes more aware that he is trying too hard.
He senses her discomfort and becomes even more cautious.
Neither can simply relax.
Their problem is not insufficient devotion.
It is the loss of ordinary trust.
Why Good Intentions Can Make a Relationship Worse
One of the most interesting ideas in the ending is that both characters are trying to be considerate.
Neither sets out to destroy the marriage.
Yet their attempts to protect one another become part of the problem.
Mitsuru’s carefulness is motivated by love, but it also prevents him from acting naturally.
Sakiko’s anxiety is understandable, but it means that even ordinary moments can be overshadowed by the possibility of abandonment.
A marriage cannot become emotionally secure simply because both people are afraid to make mistakes.
In fact, constant fear of making mistakes can make intimacy impossible.
The tragedy is that they are no longer living together freely. They are managing each other’s fears.
That is why the finale treats their continued love as insufficient to resolve the conflict.
Sakiko’s Four Previous Marriages Change Everything
Episode 9 reveals an extraordinary fact about Sakiko’s past.
Before marrying Mitsuru, she had already been married four times.
She married a securities trader at 22, a band member at 25, a civil servant at 28 and an entrepreneur at 29.
All four marriages ended in divorce.
Mitsuru is her fifth husband.
And Sakiko had not told him about those previous marriages.
This revelation changes how viewers understand her decision in the finale.
It would be easy to interpret the divorce as simply another example of Sakiko leaving a relationship.
But that interpretation misses a more interesting possibility.
Her history suggests that Sakiko has repeatedly struggled with the expectations attached to marriage.
The series does not establish that every previous marriage failed for the same reason.
Nor does it prove that Sakiko is incapable of commitment.
What it does establish is that the conventional marital structure has repeatedly failed to provide a lasting relationship for her.
Why Did Sakiko Hide Her Marital History?
The secrecy matters as much as the marriages themselves.
Sakiko’s past is not a minor biographical detail.
Four previous divorces could significantly influence how a new spouse understands her relationship with commitment, stability and personal freedom.
By keeping that history from Mitsuru, she prevents him from understanding an important part of her life.
Her secrecy also complicates any interpretation that presents her as merely the victim of Mitsuru’s behavior.
Both characters have withheld important truths.
Both have contributed to the instability of the relationship.
And both must confront the consequences.
Sakiko wants a relationship in which she can be herself, but she has also concealed parts of herself from the person closest to her.
That contradiction makes her a more complicated character than a straightforward romantic heroine.
Why Mitsuru’s Disappearances Made Marriage Unbearable
For Sakiko, marriage carries an expectation that her partner will remain present.
Not necessarily every hour of every day.
But reliably enough that their shared life feels stable.
Mitsuru’s disappearances undermine that expectation.
His absence becomes more than a practical inconvenience.
It creates uncertainty about the entire relationship.
Will he return?
When?
Why did he leave?
Will it happen again?
For someone sharing a home and a marriage, those questions can become exhausting.
The problem is not simply that Mitsuru sometimes needs distance.
It is that Sakiko cannot confidently distinguish temporary distance from abandonment.
Why Divorce Appears to Offer a Solution
Divorce changes the expectations governing their relationship.
If Mitsuru is no longer her husband, Sakiko may no longer feel compelled to measure his behavior against the promises associated with marriage.
His absence would still matter emotionally.
But it would not carry precisely the same meaning.
This is the emotional logic behind their separation.
They are not necessarily trying to stop caring about one another.
They are trying to stop making their affection depend on a structure that has become a source of fear.
However, there is an obvious objection.
Changing the relationship’s label does not automatically resolve the insecurity underneath it.
If Sakiko continues to fear losing Mitsuru, divorce alone may not make that fear disappear.
This is one of the strongest criticisms of the finale.
The series offers a different relationship structure, but viewers are entitled to question whether the characters have actually healed.
The Fireworks Tickets Reveal What Mitsuru Was Really Feeling
One of the finale’s important revelations concerns the fireworks festival tickets.
Earlier, the tickets had contributed to suspicion about Mitsuru’s behavior.
By the ending, their meaning changes.
They were intended for Sakiko.
Mitsuru had considered her dislike of crowds and made plans with her in mind.
This detail matters because it demonstrates something that the divorce might otherwise obscure.
Mitsuru was still thinking about Sakiko.
He still wanted to share experiences with her.
His affection was not merely an obligation or an empty habit.
The tickets offer concrete evidence of his continuing love.
Why the Revelation Makes the Divorce More Painful
In a conventional romantic drama, this revelation might trigger reconciliation.
A misunderstood action is finally explained.
The heroine realizes that the hero has loved her all along.
They embrace.
The marriage survives.
But Until the T-Shirt Dries refuses that familiar resolution.
The revelation proves affection.
It does not restore trust.
Sakiko can understand that Mitsuru loves her while remaining uncertain about their ability to live together as husband and wife.
The fireworks tickets answer the question “Does he love her?” but not the question “Can they build a stable marriage?”
That difference is why the revelation feels both comforting and cruel.
It gives viewers a reason to hope for reconciliation.
Then the story refuses to equate hope with a solution.
The Laundry Scene: Why Did They Keep Wetting the Clothes?
The final laundry sequence is the emotional centerpiece of the series.
Mitsuru tells Sakiko that he will leave when the laundry has dried.
It sounds like a practical arrangement.
But the two begin washing more and more household items.
Shirts are not enough.
They wash sheets, pillowcases, cushion covers and curtains.
Every additional item creates more time together.
Then comes the most revealing detail.
They secretly spray water onto the hanging laundry.
Both are trying to delay the moment when the clothes become dry.
Neither wants the farewell to happen.
What the Wet Laundry Really Symbolizes
The laundry is an ordinary domestic task.
That is why it works so well.
These are not grand romantic gestures.
They are the small activities that make up a shared life.
Washing clothes, hanging them outside and waiting for them to dry are things a married couple might do without thinking.
On their final day together, those ordinary actions become precious.
The characters are not trying to preserve a dramatic moment.
They are trying to preserve everyday life.
And by wetting the clothes, they attempt to stop time.
They cannot make the marriage work, but they can delay the moment when they must stop being husband and wife.
There is also a contradiction in the gesture.
They have agreed to separate.
Yet both secretly resist the separation.
The act of wetting the laundry reveals the emotional truth that their spoken decision cannot fully contain.
They are ready to end the marriage in principle.
They are not ready to say goodbye in practice.
Why the Title Finally Makes Sense
The title Until the T-Shirt Dries initially sounds modest, almost casual.
By the finale, it becomes a statement about how relationships are measured.
Marriage is traditionally imagined as a long-term commitment.
It promises continuity beyond a single day or moment.
But the final laundry scene introduces a radically smaller unit of time.
Stay until the clothes dry.
Be together for this afternoon.
Share this ordinary moment without demanding that it last forever.
The contrast is deliberate.
One model of love depends on permanence.
The other allows closeness to exist without a promise of permanence.
Sakiko and Mitsuru appear to be moving toward the second model.
That does not mean it is superior.
It means the series is asking whether intimacy always needs a permanent structure to be meaningful.
The Sadness Hidden Inside the Title
The title is not purely optimistic.
The laundry will eventually dry.
The afternoon will end.
Even if the characters keep adding water, they cannot stop time indefinitely.
Their effort is touching precisely because it is futile.
The title promises a temporary extension of happiness, not a permanent escape from loss.
That is what makes the final scene so memorable.
The characters know the moment cannot last.
They try to make it last anyway.
Why Reddit Viewers Were Divided Over the Divorce
The finale generated sharply different responses in the r/JDorama community.
Some viewers found the decision emotionally understandable.
They recognized that Mitsuru’s disappearances had made Sakiko feel insecure and that the expectations of marriage could intensify that insecurity.
Others were deeply frustrated.
They saw two people who clearly loved one another and felt that the drama had failed to justify why separation was necessary.
One discussion criticized the ending for becoming overly complicated after Mitsuru returned.
Another viewer argued that the characters seemed to be constructing an unconventional arrangement without truly resolving their emotional damage.
A different response suggested that Sakiko’s decision was selfish but acknowledged that the people involved might still have the right to define their own relationship.
These reactions reveal why the ending is more provocative than a straightforward breakup.
The disagreement is not about whether the characters love each other.
Most viewers can see that they do.
The disagreement is about what that love should require.
Interpretation One: The Divorce Is an Act of Emotional Honesty
Under this reading, Sakiko and Mitsuru finally acknowledge that their marriage is making them unhappy.
They stop pretending that affection alone can solve their problems.
Instead of continuing to hurt each other within a structure that no longer works, they choose a different form of connection.
The ending is bittersweet but mature.
Interpretation Two: The Divorce Avoids the Real Problems
Under the opposing reading, the characters have not meaningfully addressed the causes of their insecurity.
Mitsuru still has difficulty providing reassurance.
Sakiko still fears abandonment.
Their feelings remain unresolved.
Changing the relationship’s label may simply allow them to avoid confronting those problems directly.
The ending then becomes less an act of maturity than an elegant form of avoidance.
Both readings are supported by the emotional contradictions the finale deliberately leaves unresolved.
And that ambiguity is a major reason the ending continues to invite discussion.
Is Sakiko Selfish for Choosing Divorce?
This is perhaps the most uncomfortable question surrounding her character.
Sakiko has a history of failed marriages.
She hides that history from Mitsuru.
She continues to care for him but chooses divorce.
And her connection with Itsuki complicates the emotional picture further.
It is understandable that some viewers interpret her behavior as selfish.
But the accusation needs to be examined carefully.
Wanting to leave a marriage does not automatically make someone selfish.
A person does not lose the right to choose a different life because their partner still loves them.
At the same time, personal freedom does not erase responsibility for secrecy, mixed signals or emotional harm.
Sakiko’s right to divorce and the fairness of her conduct are separate questions.
She can be justified in deciding that marriage no longer works for her while still having made mistakes in how she handled the relationship.
Why the Series Refuses to Make Her Entirely Right
The strongest aspect of Sakiko’s characterization is that she is not an uncomplicated moral example.
She wants freedom.
She also wants affection.
She fears being abandoned.
She also resists the expectations that come with being a spouse.
These desires are not always compatible.
Her decision may be understandable without being ideal.
The finale becomes more interesting when Sakiko is treated as a flawed person making a difficult choice, rather than as someone whose decision must be either celebrated or condemned.
What Does Itsuki Represent in the Ending?
Itsuki is important because his relationship with Sakiko offers an alternative to the expectations of conventional marriage.
Their connection suggests that two people can be emotionally close without defining themselves as a traditional couple.
They can talk.
They can understand one another’s vulnerabilities.
They can maintain a connection without immediately deciding what it must become.
For Sakiko, that possibility matters.
Her history suggests that fixed expectations have repeatedly become difficult for her.
A less clearly defined relationship may feel easier to inhabit.
But this raises another question.
Is an undefined relationship genuinely more honest?
Or does it simply postpone the difficult conversations that defined relationships require?
The answer depends on whether everyone involved understands and accepts the arrangement.
A relationship without a conventional label can still require honesty, boundaries and consideration.
Removing the word “marriage” does not remove the responsibility to care about another person’s feelings.
That is why the finale’s unconventional relationship dynamics remain open to criticism.
Who Was at the Door in the Final Scene?
The ending introduces one last mystery.
Sakiko hears someone at the door and welcomes them home.
The visitor’s identity is not clearly revealed within the televised finale.
The scene invites viewers to wonder whether Mitsuru has returned, whether the visitor is Itsuki, or whether the answer is less important than the greeting itself.
A later Reddit discussion shared an official social-media behind-the-scenes clip involving Yu Aoi and Kenichi Matsuyama.
In that clip, Matsuyama appears in a playful version of the doorstep exchange.
That is a meaningful production detail.
But it should not be treated as proof that the televised ending explicitly establishes a permanent reconciliation.
The final scene itself remains deliberately open.
Why the Ambiguity Matters
The greeting suggests warmth and familiarity.
Someone is welcome in Sakiko’s home.
The important change may be that she no longer needs the visitor’s presence to fit a conventional definition of family.
She can welcome someone without the series spelling out what that person must be to her.
But there is a less optimistic interpretation.
Perhaps the ambiguity allows the story to avoid answering the difficult practical questions raised by the divorce.
If Mitsuru continues to visit, what has really changed?
If Sakiko remains emotionally involved with more than one person, how will those relationships work?
The finale offers an image of acceptance.
It does not provide a detailed plan for the future.
That is both its poetic strength and its narrative vulnerability.
Was the Ending Actually Happy?
It depends on how happiness is defined.
If happiness means that Sakiko and Mitsuru remain married, the ending is unhappy.
If happiness means that both can finally acknowledge their feelings without forcing themselves into an uncomfortable marital structure, the ending offers hope.
But neither interpretation captures the entire emotional effect.
The laundry scene is heartbreaking because their affection remains genuine.
The divorce is unsettling because their problems remain complicated.
And the final greeting is comforting because it suggests that separation does not necessarily mean complete emotional abandonment.
The ending is therefore neither a conventional tragedy nor a conventional happy ending.
It is an attempt to imagine a relationship that survives after its original form has ended.
The characters lose their marriage, but the story leaves open the possibility that they have not lost each other.
Whether that is enough depends on what viewers believe love should provide.

Who had four previous marriages?
Sakiko, not Mitsuru. She reveals that she had been married four times before marrying Mitsuru.
Why did they keep spraying water on the laundry?
Both wanted to delay the moment when Mitsuru would leave. Keeping the laundry wet allowed them to extend their remaining time together.
What was the meaning of the fireworks tickets?
The tickets were intended for Sakiko, revealing Mitsuru’s continued consideration and affection for her.

The televised finale does not explicitly confirm a conventional marital reconciliation. Their emotional connection continues, but the precise future of their relationship remains open.
Who was at Sakiko’s door at the end?
The televised ending does not clearly show the visitor. An official behind-the-scenes clip featuring Kenichi Matsuyama has fueled discussion, but the on-screen conclusion remains ambiguous.
Is Until the T-Shirt Dries based on a novel?
The drama is an original screenplay by Miku Ubukata, rather than a straightforward adaptation of an existing novel.
Final Verdict: They Did Not Divorce Because Love Was Gone
The ending of Until the T-Shirt Dries is difficult to accept because it challenges one of romance television’s most familiar assumptions.
We are accustomed to believing that love, once proven, should be enough.
The fireworks tickets prove that Mitsuru cares.
The wet laundry proves that neither wants the separation to happen.
Their tears and hesitation prove that the marriage still matters.
Yet the divorce goes ahead.
Why?
Because affection and security are not the same thing.
Sakiko can love Mitsuru and still fear his disappearances.
Mitsuru can love Sakiko and still feel unable to behave naturally around her.
They can want each other while recognizing that their shared home has become a place of anxiety.
Whether divorce genuinely solves those problems remains debatable.
The series does not offer an easy answer.
But the final laundry scene reveals something essential about both characters.
They are not trying to escape each other. They are trying to escape the fear that has come to define their marriage.
And perhaps that is why the image of two people secretly wetting their laundry is more powerful than a dramatic farewell.
They have decided that they cannot remain husband and wife.
But neither is ready for the ordinary happiness of being together to end.
Their marriage ends when the laundry dries. Their love does not necessarily end with it.
That is the beautiful—and deeply frustrating—contradiction at the heart of the finale.
