Spoiler warning: This article contains major spoilers for Diés Iraé (2025).
One of the biggest unanswered questions in Diés Iraé is surprisingly not about Philip.
It is about Kani.
We know that Kani dies before most of the supernatural events involving Rohan begin.
We know that Rohan had a relationship with her and then abruptly disappeared from her life.
We later learn that Philip had been obsessively watching her.
And we discover that Philip himself died before Kani.
But the film never gives us a simple scene explaining exactly why Kani died.
That has left viewers asking the same question:
Why did Kani kill herself?
Was it because Rohan ghosted her?
Was Philip’s spirit already haunting her before she died?
Did the two pressures combine?
Or is the movie intentionally refusing to give Kani’s death a single explanation?
The most careful answer is:
Kani appears to have died by suicide, but the film never explicitly confirms one definitive reason why.
And that missing explanation may be more important than it first appears.
What Do We Actually Know About Kani?
Before discussing theories, we need to separate what the film establishes from what viewers infer.
Kani and Rohan had been romantically involved.
For Rohan, however, the relationship was casual.
He eventually cut contact with her.
Later, Rohan learns that Kani has died.
When he visits her grieving family, he takes a pink hair clip from her room.
Soon afterward, paranormal disturbances begin inside his home.
Rohan naturally assumes the obvious:
Kani has returned because of what he did to her.
The movie wants us to believe that too.
At least initially.
Rohan’s Guilt Makes Kani the Perfect Suspect
Rohan has an obvious reason to fear Kani.
He treated her badly.
He disappeared from her life.
Now she is dead.
Then supernatural events begin immediately after he takes something from her room.
Everything appears to connect perfectly.
Kani loved Rohan.
Rohan abandoned Kani.
Kani died.
Rohan disturbed her belongings.
Kani returned.
It is almost too perfect.
And Diés Iraé eventually reveals that it is.
Because the violent spirit terrorizing Rohan is not simply Kani.
The investigation leads toward another person:
Philip.
Philip Changes the Entire Meaning of Kani’s Death
Philip had been obsessed with Kani.
He watched her from a distance.
His fixation continued even though he never had a normal romantic relationship with her.
Eventually, Rohan discovers something much worse.
Philip is already dead.
The man supposedly believed to have gone abroad is actually the decaying corpse hidden inside Elsamma’s house.
And attached to that corpse is something belonging to Kani:
her chilanka — her anklet.
That discovery transforms the story.
Philip’s obsession did not necessarily end with his death.
If his spirit continued following Kani afterward, then Kani may have experienced the same kind of supernatural harassment that Rohan later experiences.
And that creates a disturbing possibility.
Theory 1: Kani Killed Herself Because Rohan Abandoned Her
This is the most obvious explanation.
Rohan ghosts her.
Kani remains emotionally attached to him.
She later dies by suicide.
On a simple chronological level, the conclusion seems easy:
Rohan broke her heart, and Kani could not cope with it.
The film also deliberately encourages Rohan — and the audience — to feel this guilt.
It gives the early haunting emotional logic.
Rohan doesn’t merely fear a ghost.
He fears consequences.
If Kani died because of him, then her return becomes a form of judgment.
That makes excellent horror storytelling.
But there is a problem.
The Movie Never Actually Says Rohan’s Rejection Caused Her Death
This distinction matters.
Kani’s feelings for Rohan are real.
Rohan’s treatment of her is cruel.
But neither fact proves that his rejection alone caused her suicide.
The film does not give us a definitive confession, suicide note or flashback establishing:
“Kani died because Rohan left her.”
That explanation is partly created by Rohan’s guilt and by the audience filling in a missing piece.
And once Philip’s story is revealed, another explanation becomes possible.
Theory 2: Philip’s Ghost Was Already Haunting Kani
This is the darker theory.
Philip dies.
But his obsession with Kani continues after death.
His spirit remains attached to the physical world.
Kani then begins experiencing Philip’s supernatural presence.
If so, what happens to Rohan later may give us a clue about what happened to Kani earlier.
Think about Rohan’s experience.
He is attacked.
He is terrified inside his own home.
He cannot initially understand what is happening.
The supernatural presence invades what should be his safest space.
His perception of ordinary life begins collapsing.
Now imagine Kani experiencing something similar.
Except she doesn’t have Madhusudanan helping her.
She doesn’t know Philip is dead.
She may not even understand that the man who watched her while alive is still following her.
Under this interpretation:
Philip stalked Kani in life — and continued stalking her after death.
Reddit Viewers Noticed Exactly This Possibility
This interpretation isn’t something we need to invent to fill the plot.
Viewers independently arrived at it after watching the film.
Some questioned whether Rohan’s rejection was really enough to explain Kani’s suicide.
Others proposed that Philip’s spirit had already begun tormenting her and eventually pushed her psychologically toward death.
That theory also explains why Kani’s death is left strangely underexplained.
Perhaps the missing information isn’t:
“Why was she so upset about Rohan?”
Perhaps it is:
“What was happening to Kani after Philip died?”
The Timeline Makes Philip Important
The order of events matters.
Philip’s death occurs before the haunting that Rohan experiences.
His corpse remains hidden.
His spirit remains connected to Kani’s belongings.
Then Kani dies.
Later, Rohan takes her hair clip.
And the supernatural activity follows him.
That creates a possible chain:
Philip becomes obsessed with Kani while alive.
↓
Philip dies.
↓
His obsession continues after death.
↓
Kani experiences his presence.
↓
Kani dies.
↓
Rohan takes Kani’s hair clip.
↓
Philip’s spirit follows the connection to Rohan.
If this reading is correct, Kani and Rohan are not two unrelated haunting victims.
They are consecutive victims of the same obsession.
But Why Would Philip Hurt Kani If He Loved Her?
This is the strongest objection.
Philip is obsessed with Kani.
So why would his spirit torment the woman he supposedly loves?
Because Diés Iraé does not really present Philip’s feelings as healthy love.
His behavior while alive is already defined by watching, following and possessing.
He doesn’t need Kani’s consent to maintain the relationship inside his own mind.
That is obsession.
And obsession can become threatening precisely because the obsessed person believes possession is affection.
Philip doesn’t necessarily need to want Kani dead.
His refusal to leave her alone may itself be destructive.
That distinction matters.
Philip harming Kani does not mean he stopped wanting her.
It may mean that what he called love was never love in the first place.
The Chilanka Makes the Possession Theme Stronger
Kani’s anklet is one of the most important objects in the movie.
It eventually appears attached to Philip’s corpse.
That is not merely a random horror prop.
Symbolically, it is disturbing.
Philip possesses something intimately connected to Kani.
Even in death.
The object becomes part of the mechanism keeping his supernatural presence active.
So Philip’s relationship with Kani continues to be expressed through possession.
He could not have her.
But he could keep something that belonged to her.
And after death, that attachment becomes literal.
Then What About Kani’s Hair Clip?
The hair clip creates a fascinating parallel.
Philip has Kani’s chilanka.
Rohan takes Kani’s hair clip.
Both men possess something belonging to Kani.
But the consequences are completely different.
Philip’s possession comes from obsession.
Rohan’s act is casual — almost careless.
Yet taking the hair clip seems to open the path through which the haunting reaches Rohan.
This creates a recurring idea:
Kani’s personal objects become connections between people who wanted something from her.
Even after Kani dies, other people continue carrying pieces of her story.
Was Kani Herself Haunting Rohan Too?
Probably, at least in some form.
This is where the movie becomes more complicated than a simple “wrong ghost” twist.
The violent presence is ultimately associated with Philip.
But several moments feel different.
A presence sits beside Rohan.
His hair is touched gently.
The final scene again suggests that the supernatural story may not have ended when Philip is released.
That opens the possibility that both spirits are present, but their behavior differs.
Philip is territorial and violent.
Kani’s presence appears more intimate.
If so, the early haunting may deliberately mix the two spirits so that Rohan — and the audience — cannot immediately distinguish them.
Kani Returning to Rohan Does Not Prove She Died Because of Him
This is important.
One argument against the Philip theory is:
If Kani returns to Rohan after death, doesn’t that prove she was obsessed with Rohan and therefore killed herself because he rejected her?
Not necessarily.
Two different statements can both be true:
Kani remained emotionally attached to Rohan.
and
Rohan’s rejection was not the sole cause of her death.
Human motives are rarely that simple.
Kani could still care about Rohan while also being psychologically devastated by supernatural harassment, loneliness or other pressures the film does not fully show.
Her return tells us something about her attachment.
It does not provide a medical-style diagnosis of why she died.
Theory 3: Rohan and Philip Both Contributed to Kani’s Collapse
This may be the most balanced interpretation.
Instead of searching for one villain responsible for Kani’s suicide, consider the situation she experiences.
Rohan abandons her.
She is isolated.
Philip has already stalked her.
Philip dies but may continue following her supernaturally.
Kani may begin experiencing frightening events that nobody around her understands.
And she appears to have little meaningful support.
Under this interpretation, there isn’t one clean cause.
There is accumulation.
Emotional abandonment + isolation + Philip’s obsession + possible supernatural harassment.
That combination fits the film better than reducing Kani’s death to:
“She killed herself because a boyfriend ghosted her.”
Why Doesn’t the Film Explain Her Death More Clearly?
There are two ways to look at this.
The first is critical:
The movie simply leaves an important plot point underexplained.
Many viewers clearly felt this way.
Kani’s death launches the entire story, so naturally audiences want to know exactly what happened to her.
That criticism is legitimate.
But there is another interpretation.
The absence of a definitive explanation keeps Kani from becoming a simple horror-movie equation:
Boy rejects girl → girl commits suicide → girl becomes ghost.
Instead, once Philip is revealed, we are forced to reconstruct Kani’s experience ourselves.
And that reconstruction makes her story much darker.
We See Kani Mostly Through Men
This is an important part of the film.
Rohan remembers Kani through their relationship.
Philip sees Kani through obsession.
Her family sees their dead daughter.
The investigation sees a victim.
The supernatural plot turns her into a possible ghost.
But Kani herself gets relatively little opportunity to explain what she experienced.
That may be why the question remains so frustrating.
Everyone has a version of Kani.
Kani’s own version is largely missing.
And perhaps that is why viewers keep asking what really happened to her.
Rohan’s Guilt Is Real Even If He Didn’t Cause Her Death
We should also avoid going too far in the opposite direction.
If Philip’s spirit contributed to Kani’s death, that does not suddenly make Rohan a good person.
He treated Kani carelessly.
He disappeared rather than dealing honestly with the relationship.
The film deliberately establishes this moral weakness.
But moral responsibility and causal responsibility are different.
Rohan can have treated Kani badly without being the reason she died.
That distinction is essential.
Otherwise the movie becomes much simpler than the supernatural mystery suggests.
Philip May Be the Hidden Link Between Both Death and Haunting
If the Philip theory is correct, suddenly several disconnected parts of Diés Iraé align.
Why does Kani die?
Why does the haunting continue afterward?
Why is Philip connected to Kani’s possessions?
Why does the supernatural presence become violent around Rohan?
Why does destroying the physical connection to Philip matter?
The answer may be the same:
Philip’s obsession did not end when Philip died.
Death didn’t cure it.
It transformed it.
Kani may have been its first supernatural victim.
Rohan becomes the next.
What the Film Actually Confirms — and What It Doesn’t
This distinction is worth making clearly.
The film establishes:
- Rohan and Kani had a relationship.
- Rohan later cut her off.
- Kani died.
- Philip had been obsessed with Kani.
- Philip also died.
- Philip’s corpse remained hidden.
- Kani’s chilanka became connected to Philip’s corpse.
- Philip’s spirit is central to the violent haunting of Rohan.
The film does not clearly establish:
- that Rohan’s rejection alone caused Kani’s suicide;
- that Philip directly killed Kani;
- that Philip’s ghost definitively drove Kani to suicide;
- or one single confirmed motive for Kani’s death.
That is why any explanation claiming absolute certainty goes further than the movie itself.
So Did Philip Kill Kani?
Not in the straightforward sense.
We are not shown Philip physically murdering Kani.
And saying:
“Philip killed Kani”
would be too strong based on the evidence the film gives us.
A more defensible interpretation is:
Philip may have continued haunting Kani after his own death, contributing to the psychological state that eventually led to her suicide.
That remains interpretation rather than confirmed fact.
But it explains more of the movie than the simple breakup theory does.
The Saddest Reading of Kani’s Story
Perhaps the darkest interpretation is that Kani was trapped between two very different kinds of male selfishness.
Rohan wanted her only while the relationship was convenient.
Philip wanted her whether she wanted him or not.
One man abandoned her.
The other refused to leave her alone.
Those behaviors are opposites.
But both deny Kani control.
Rohan decides when their relationship ends.
Philip decides that his obsession never ends.
Even after death, Kani remains caught between them.
That makes her story considerably more tragic than simply being “the ex-girlfriend who became a ghost.”
Final Answer: Why Did Kani Die in Diés Iraé?
Diés Iraé does not explicitly confirm one definitive reason for Kani’s suicide.
Rohan ghosting her clearly matters emotionally, and the film initially encourages us to connect his behavior with her death.
But the later revelation about Philip creates a stronger and darker possibility:
Philip’s obsession may have continued after his death, and Kani may have been experiencing his supernatural harassment before Rohan ever was.
That interpretation would explain why Philip’s spirit remains connected to her belongings and why Rohan later becomes another target.
The most reasonable conclusion, therefore, is not:
“Kani killed herself because Rohan rejected her.”
Nor can we state as fact:
“Philip killed Kani.”
Instead, the movie leaves us with a combination of factors — abandonment, isolation, obsession and possibly supernatural torment — without telling us exactly where one ends and another begins.
And perhaps that’s why the question has stayed alive long after the credits.
Philip’s mystery is eventually explained.
Kani’s never completely is.
