DearX K-Drama has taken the world by storm, and it’s not hard to see why. Back Ah Jin, the central character, is one of the most interesting and well-written roles in recent K-drama history.
She is the kind of character that makes you hate her and understand her simultaneously. The drama’s plot is packed with tension, psychological twists, and emotional moments that keep you glued to your screen from start to finish.
Every single episode reveals layers of trauma, revenge, and human complexity that few shows dare to explore.
Kim Yoo Jung’s portrayal of Baek Ahjin is nothing short of phenomenal. From the cold, sociopathic exterior to moments of vulnerable humanity, she brings a depth to Ahjin that is impossible to ignore.
Her dedication to the role is evident in every facial expression, every tremble of fear, and every flash of anger that defines her character.
Baek Ahjin: The Complex Sociopath
Back Ah Jin was such an interesting and well-written character, the kind that makes you hate her just as much as you understand her. Kim Yoo Jung fully embodies this complexity.
Her acting as Baek Ahjin is absolutely crazy , it feels as though she transformed herself into an actual sociopath. The amount of dedication and hard work poured into this character deserves endless praise.
She is a sociopath, born evil, and the narrative never tries to justify her actions. The show clearly communicates that she needed to be stopped, and Junseo’s attempts to intervene are part of that story.
The trauma Baek Ahjin carries is palpable. From childhood betrayals to repeated emotional manipulation, she navigates a world filled with obstacles, betrayals, and unfulfilled desires.
Her phrase,
“why do I always have to suffer?”
resonates throughout the series, capturing the essence of her pain. Episode 11, in particular, exposes a side of Ahjin she rarely shows , trembling in fear, struggling with anger, and haunted by her past traumas. Every look, every subtle movement, communicates volumes about her inner turmoil.

Junseo: A Complicated Ally and Heartbreak
Junseo’s role in DearX is equally layered. The scenes where he deletes his childhood pictures before disappearing from his mother’s life are psychologically chilling, showing the extreme measures he takes in a world of moral ambiguity.
His love for Ahjin is complicated , protective yet destructive at times. He truly believed his actions were the only way to manage the chaos surrounding Ahjin, but as viewers, we feel the emotional cost of these decisions.
The dynamics between Ahjin and Junseo force us to question morality, loyalty, and love. While some audiences criticize Junseo, understanding his intentions reveals the depth of his character.
He acts out of devotion and desperation, and the tragedy of unreciprocated understanding is central to the story.
“This is the end, right?” “I can’t stop. I wouldn’t stop. If you knew how dangerously I’m hanging on to this position, you wouldn’t tell me to stop.” OKAY SO, SHE WAS INSANE FOR SAYING THIS
Kim Jaeoh: Loyalty and Sacrifice Personified
Kim Jaeoh is perhaps the most heartbreaking character in DearX. His loyalty and love for Ahjin run so deep that it hurts to witness the sacrifices he makes. His words
“Maybe it’s because I don’t have much in my life, but you’re everything to me. Every time I help you get what you want, every time I make things easier for you, you have no idea how useful I feel. So go ahead Ahjin, use me all you want, that’s what I want,”
perfectly capture his selflessness and the pain of loving someone who cannot fully see or acknowledge him.
Jaeoh’s devotion never wavers. He becomes Ahjin’s only safe space, the one person she can be vulnerable with, yet even his presence can’t alter her path of revenge and survival. The emotional weight of his unrequited loyalty and the tragic choices he faces make him one of the most memorable characters in the drama.
aeoh helped her to protect herself from this psycho but with his life.
Dohyuk: The Psychopath Who Shattered Her World
Dohyuk’s manipulation of Ahjin demonstrates the extreme psychological complexity within the series. From driving her to the brink of insanity to acting as a seemingly caring husband, he reconstructs her worst moments and forces her through repeated traumas.
His control over her is chilling , he orchestrates situations that mirror her past pain, pushing Ahjin into a psychological trap that tests her endurance and willpower.
Every action Dohyuk takes reinforces his role as a twisted antagonist. The way he gaslights Ahjin, controls her environment, and manipulates her mind is a testament to the show’s dark, thrilling narrative. The drama doesn’t just show physical danger; it delves deep into emotional and psychological torment.
The Emotional Rollercoaster of DearX
The final episodes of DearX are emotionally overwhelming. Ahjin’s journey from cold, calculated sociopath to a more reflective, humanized character is both fascinating and gut-wrenching. Her realization,
“I thought there was nothing left that could tie me down. But it was you. My final shackle,”
encapsulates the emotional climax of the series — love, trauma, and revenge intersecting in one powerful moment.
Every supporting character, from Junseo to Jaeoh, adds depth to Ahjin’s story. Their actions, motivations, and interactions with Ahjin create a rich tapestry of tension, emotion, and suspense. Even in moments of extreme darkness, there are glimpses of humanity, hope, and resilience.
