Dear X ending is a brutal reminder that only the strongest monster survives. Here’s a complete breakdown of Episodes 11–12, character fates, and the final message behind Baek Ah-jin’s disappearance.
1) After the Shim Sung-hee Incident — Baek Ah-jin Begins to Collapse
Episode 11 picks up with the aftermath of Shim Sung-hee’s home invasion.
The attacker — a high school classmate posing as an obsessive fan — is arrested, yet the scandal spreads everywhere.
The past of both Sung-hee and Ah-jin resurfaces like a buried corpse breaking through dirt.
Meanwhile, the novel 〈Dear X〉, written by Yoon Jun-seo, becomes suspiciously connected to Ah-jin’s real life:
“Isn’t this basically Baek Ah-jin’s story?”
A broadcasting station suggests turning it into a documentary.
Jun-seo rejects the idea publicly — though his cold eyes imply something hidden.
This moment subtly marks the beginning of the Dear X ending, where truth and fiction collide in the most destructive way.
Ah-jin’s condition worsens rapidly.
Severe stress causes memory loss.
She even forgets that she asked Kim Jae-oh to dig into her husband Moon Do-hyuk’s past.
Her mind fractures before our eyes — a key psychological setup for the Dear X ending.
2) The Husband Who Was Supposed to Save Her — Becomes Her Real Hell
Do-hyuk’s real identity is exposed piece by piece:
- His previous wife: mental breakdown after marriage
- Shim Sung-hee: manipulated into violent obsession
Kim Jae-oh uncovers the truth:
Do-hyuk is a sociopath skilled at psychological torture.
He:
- Prescribes controlling medication
- Eavesdrops and tracks her
- Plants her past trauma into the film script
His goal is horrifyingly simple:
Turn Ah-jin into a doll that breathes only for him.
Suspicion is overflowing,
but the lack of evidence suffocates her.
The power imbalance between them becomes a core engine of the Dear X ending.
3) Kim Jae-oh — The Man Who Walks Into Death for Evidence
Always calling her “Boss”.
Always by her side.
Always the most loyal.
Jae-oh makes his final decision:
He will become the evidence that destroys Do-hyuk.
His trap is perfect:
- Cameras installed in an abandoned construction site
- Live auto-backup to cloud + Ah-jin
- Do-hyuk’s name intentionally invoked during the attack
In his final moments,
his memories of Ah-jin flash like the last light leaving the world.
His death becomes:
Ah-jin’s leash to choke Do-hyuk.
A brutal, beautiful sacrifice.
His loyalty is ultimately what pushes the Dear X ending toward full catastrophe.
4) Blue Dragon Awards — The Peak and the Fall Happen Simultaneously
Jae-oh’s sacrifice leads Ah-jin to a new peak:
her movie becomes a hit,
and she becomes the top candidate for Best Actress.
But on the same night…
A documentary on female sociopaths airs live.
- Testimonies from classmates
- Victims like Sung-hee and Baek Seon-gyu
- Her father’s death re-investigated
The final blow?
Yoon Jun-seo is the key witness.
“Before she becomes a worse monster,
I’ll drag her down with my own hands.”
Backstage, Ah-jin watches the broadcast.
Her crown shatters.
Betrayal. Fear. Rage. Collapse.
This explosive contrast — red carpet vs. accusation — is one of the most symbolic beats of the Dear X ending.
5) “You’ll never change.” vs. “I’ll never stop.”
Ah-jin runs — glittering dress, broken heels, shaking breath.
Not knowing where to go.
Only knowing she must run.
Jun-seo finds her.
The last drive begins.
Inside the car:
Jun-seo: “Let’s stop now. No more hurting anyone. Just look at me.”
Ah-jin: “I can’t stop. I won’t stop.”
Jun-seo: “I thought you could change.”
Ah-jin: “I never change.”
Jun-seo cries.
He slams the accelerator.
The car shoots through the guardrail.
A fatal plunge.
Love ends in a scream — perfectly encapsulating the emotional core of the Dear X ending.
6) The Cliff — A Choice That Defines Them
From the wreck:
- Jun-seo: trapped and dying
- Ah-jin: barely conscious, crawling out
Jun-seo reaches out — one last plea.
She pushes his hand away.
She climbs alone.
She chooses survival — over love, over guilt, over humanity.
Later:
- Jun-seo → declared dead
- Ah-jin → body not found → legally dead
A niche with her name appears in a columbarium.
But a living woman places flowers before it.
She walks away.
Baek Ah-jin is “dead.”
A new monster lives.
This is the final stroke of the Dear X ending:
the world believes she is gone, but she alone rewrites her existence.
Character Fates & Meaning
| Character | Fate | Interpretation |
|---|---|---|
| Baek Ah-jin | Alive, identity erased | Cuts every chain — even her name |
| Yoon Jun-seo | Dead | Love twisted into self-destruction |
| Kim Jae-oh | Dead | Devotion turned into cold evidence |
| Moon Do-hyuk | Alive | The worst monsters often survive |
The Dear X ending refuses justice.
It chooses truth — the uncomfortable one.
Webtoon vs Drama: Why So Different?

|---|---|
| Twisty thriller with lingering mystery | Full descent into destruction |
| Child / relationship continuity included | Removed for darker impact |
| More room for psychology | Compressed into explosive chaos |
The drama is a dopamine-fueled noir,
pushing the downfall to the extreme seen in the Dear X ending.
