Dear X Finale Twist Finally Confirms Who Dies

Dear X doesn't tiptoe to the finish line. The finale swerves away from the webtoon and goes for a darker, messier outcome. If you were hoping for redemption arcs, this show laughs in your face and keeps driving.

Who lives, who dies (finale spoilers)

• Kim Jae-oh: dead. He engineers his own demise to trap Moon Do-hyeok on video.
• Yoon Jun-seo: dead. He drives off a cliff with Baek Ah-jin in the car.
• Baek Ah-jin: alive. She crawls out of the wreck, leaves Jun-seo to die, and disappears.

How it all goes down

The episode opens with Baek Ah-jin's carefully curated life cracking under pressure from her husband, Moon Do-hyeok. Instead of a clean confrontation, the show gives us something way colder: Kim Jae-oh quietly builds a trap. With help from Do-kang, he plants cameras and spyware, then lures Do-hyeok's henchmen to a rooftop so the footage clearly shows Do-hyeok ordering what happens next.

Jae-oh is pushed to his death. That was the plan. His sacrifice hands Ah-jin the leverage she needs to flip the power dynamic with her manipulative husband. The fallout? She regains control and her career spikes again thanks to the success of her film Amen to Nothing.

Then Yoon Jun-seo gets the files tied to Jae-oh's death, puts the pieces together, and finally accepts who Ah-jin really is. He gives her one last chance to prove him wrong:

"How long are you going to keep living like this?"

She refuses to change. So Jun-seo helps drop a documentary exposing Ah-jin's manipulation and crimes, timed to hit right as she's accepting a Best Actress trophy at the Blue Dragon Awards. She bolts from the ceremony in a panic, and Jun-seo catches up, gets her in the car, and makes a choice that is as bleak as it sounds. He floors it off a cliff, telling her they should "just go to hell together." It looks like they both die on impact.

The final twist

Not quite. A last flashback reveals Ah-jin surviving the crash. She claws out of the wreck, looks down at a dying Jun-seo, laughs, and vanishes into hiding instead of helping him. It's brutal, it's mean, and it seals the show's point of view on her character.

So yes, the series leaves the webtoon behind and chooses a nastier endgame: Jae-oh sacrifices himself to give Ah-jin power, Jun-seo tries to take her down with the truth, and Ah-jin still walks away. Cold.
