The story revolves around Yoon Sojeong, a highly capable deputy manager in the External Relations Team, who finds herself entangled in a complicated and highly intimate relationship with Muhyeok. Their interactions, even when indecent, are characterized by a strange mix of desire and innocence, particularly in Sojeong's reactions.

A year passes, and Sojeong decides to strategically end things, citing marriage as the reason for the breakup. This sudden move deeply provokes Muhyeok, who knows the depth of their connection and her smart yet calculated actions. He confronts her, reminding her that she was fully aware of his possessive and intense nature when they started.

Despite pretending to be fine with her decision, Muhyeok cannot quench the intense thirst he feels for Sojeong. He takes her again, fueled by desperation and obsession. His feelings are clear: he won't let her go easily.

“People’s hearts change. If you ever change your mind, just tell me. Even after you’re married—it doesn’t matter.” Muhyeok lays down a possessive ultimatum, highlighting the obsessive and dramatic nature of their relationship, promising continued intensity regardless of her marital status.
