In Dear X episode 10, Ah-jin tries to look calm even though everything around her is burning down. The smile she gives Do-hyuk when she accepts the ring feels more like manners than joy.
She even reassures Jae-oh that she is okay and promises to call later, though anyone can tell she is falling apart. Her world appears clean and tidy from the outside, but the cracks are huge.
Jun-seo faces his own loss at the same moment. His grandfather’s passing casts a heavy shadow, and the funeral turns chaotic very quickly. His mother stirs trouble over inheritance, drawing every eye in the room.
Later, she admits she did it on purpose because the relatives were already circling the wealth like predators, and that confession shows how exhausted she truly is.
Jun-seo meets Ah-jin afterward. He wants to know why she hid the truth about not being his biological mother’s son. His voice carries hurt more than frustration. He tells her he could endure anything for her, but the silence was what cut him the deepest.
Do-hyuk and Ah-jin move forward with their Italy wedding plans in the middle of all this emotional chaos. They present themselves like a strong, confident pair, yet something odd hangs between them.
Re-na heads to the airport and gently tells Jun-seo that he should let Ah-jin go. Her tone is soft but unwavering, and that pushes him to step away from his writing and pause his life for a while. He seems lost, but there is a small hint that healing might begin.
Secrets, Floors, Knives, and a Very Bad Marriage Vibe
Ah-jin then asks Do-hyuk if she can use his study for her script. The caretaker blocks her, which feels weird already. Do-hyuk says they should rehearse together instead, like he wants control. It feels like a nice suggestion at first, but the energy is off.
During the practice, she plays a murderer in the script. Do-hyuk suddenly asks if she has ever killed someone or wanted to.
That question drops like a brick. Ah-jin freezes because it feels too real and too pointed. Her eyes show she wants to run but can’t.
Then the episode jumps into a wild twist. Baek Ah-jin and Do-hyuk’s marriage becomes the hottest news in the country.
Everyone talks about it online. Jae-oh and Jun-seo watch quietly, not celebrating.
They look confused and broken because everything happened too fast. Ah-jin says yes to Do-hyuk because he promises to clean her name. He says he will fix the mess in her life.
It sounds sweet, but the vibe shifts fast when his obsessive nature starts leaking out. He has a whole floor in his house locked. Only he can enter. That detail screams “big secret” even if no one says it out loud.
When Ah-jin asks if she can practice on that floor, he refuses. He smiles but it feels cold. He tells her he will rehearse with her. Again, it sounds caring, but the tone feels controlling.
He also talks about his first wife & he says she annoyed him, and when that happened, he could go to extreme levels. He even hints at divorce like it’s a threat. Ah-jin listens with a stiff smile. She knows something is wrong but pretends everything is okay. Her survival mode is loud.
At this point, the stress is building, and the drama feels sharp. This moment also ties into the Dear X episode 10 ending explained, because the tension sets up the final act. Every little detail hints that the truth is close.
Jun-seo tries to move on. Lena leaves quietly and chooses her own peace. Everyone seems to walk away from Ah-jin except Do-hyuk, who clings tighter.
Then the final sequence arrives, and everything blows up. Sung-hee enters Ah-jin and Do-hyuk’s house wearing a maid outfit. She looks unhinged but determined.
Ah-jin steps outside into the sun to practice her lines. She tries to focus, but the moment feels heavy. Sung-hee suddenly appears behind her with a knife. She blames Ah-jin for ruining her life.
Her voice shakes with rage and hurt. Ah-jin fires back with calm truth. She tells Sung-hee that she is facing the consequences of her actions. The confrontation gets fierce and personal.
Sung-hee tries again to stab her. Ah-jin shoves her back on instinct. The fall is violent. Sung-hee’s face gets slashed deeply.
Blood rolls down her cheek like a red tear. Ah-jin lets out a shaky laugh that feels both scared and relieved. It’s the type of laugh a person makes when they can’t tell if they won or survived.
Right then, Do-hyuk arrives. He sees the whole scene.
His expression freezes. Everything is out of control, and he steps right into the chaos. This moment completes the arc of Dear X episode 10 ending, because the ending shifts the entire story.
The final shot leaves a strong punch. Ah-jin stands shaking. Sung-hee bleeds. Do-hyuk watches. The room feels like a bomb waiting to explode again.
