Marry My Husband - Characters & Cast

Initially, her sole motivation is revenge: to make her husband and best friend pay for their betrayal by having them marry each other. As the series progresses, her motivation evolves. It becomes less about pure vengeance and more about securing her own happiness and protecting the new, loving relationships she has formed. She fights not just to punish the wicked but to build a future she can look forward to.

Kang Ji-won begins as a terminally ill cancer patient who is timid, selfless to a fault, and a victim of constant manipulation. After being murdered and sent back in time, her arc is one of radical transformation. Fueled by a desire for revenge, she evolves from a passive victim into a strategic and assertive woman. She learns to stand up for herself, outmaneuver her enemies, and build her self-worth. Her journey culminates in her not only achieving her revenge but also finding genuine love and happiness, completely rewriting her destiny from a tragedy to a triumph.

His primary motivation is his deep, unwavering love for Kang Ji-won. Having regretted not being able to protect her in their past lives, he dedicates his second chance entirely to ensuring her safety and happiness. Everything he does, from confronting her abusive husband to revealing corporate secrets, is aimed at steering her away from her tragic fate.

Yoo Ji-hyuk is initially presented as a stern, enigmatic marketing manager. It is soon revealed that he, too, has traveled back in time. In the first timeline, he was in love with Ji-won from afar and died tragically after her funeral. His arc is about moving from a silent observer to an active protector. He uses his knowledge of the future and his resources to guide and shield Ji-won. His journey is one of learning to express his long-held feelings and actively fighting for the woman he loves, becoming the unwavering pillar of support she never had.

Min-hwan is motivated by pure selfishness, greed, and entitlement. He desires a comfortable life without responsibility, which is why he leeches off Ji-won. His actions are driven by his immediate wants, whether it's money, gratifying his ego, or avoiding accountability. He consistently chooses the path that seems easiest for him, regardless of who it hurts.

Park Min-hwan is a selfish, misogynistic, and immature mama's boy who sees his wife Ji-won as more of a servant than a partner. His character does not have a growth arc; instead, he devolves. As Ji-won slips from his control, his worst traits—greed, cowardice, and violent tendencies—are amplified. He is easily manipulated by both Su-min and later Oh Yu-ra. His path is a downward spiral, leading him to fulfill the tragic fate originally meant for Ji-won, ultimately being killed during a confrontation with Su-min.

Su-min is motivated by a pathological envy of Kang Ji-won. She feels a compulsive need to steal Ji-won's life—her boyfriends, her projects, her happiness—to validate her own existence. Her actions stem from a deep-seated belief that Ji-won's happiness is something that rightfully belongs to her, combined with a desperate need to always appear as the victim.

Jeong Su-min presents herself as Ji-won's sweet and loyal best friend, but is in reality a deeply manipulative and narcissistic individual with a severe inferiority complex. Her arc is one of escalating obsession and villainy. She has always coveted everything Ji-won has. When Ji-won begins to empower herself, Su-min's manipulative tactics become more desperate and dangerous. She succeeds in marrying Min-hwan, only to find the miserable life she unknowingly inherited. Her journey ends in ruin, imprisoned for murder and attempted murder, consumed by a hatred she can't let go of.
