Mania

Choi Mun-hyeok, a former street thug, has always lived by a single rule: protect his younger siblings at any cost. When a brutal defeat in an underground fighting ring leaves him stripped of his freedom and sold at auction to the wealthy Seo Yeonjin, Mun-hyeok is forced into an unthinkable compromise. To secure his family’s safety, he willingly surrenders his autonomy, accepting a life bound to another man's control. For Yeonjin, however, familial devotion means nothing. Driven by a desire to provoke his billionaire father, he orchestrates a scandalous arrangement with his newly acquired subordinate. He demands that Mun-hyeok serve him completely—both as a dutiful attendant in daily life and as a willing partner behind closed doors. What begins as a calculated act of rebellion fueled by twisted, carnal indulgence soon spirals beyond their expectations. As their intense encounters grow increasingly consuming, both men find themselves entangled in emotions far deeper than either intended to feel. In a relationship built on power and provocation, they must navigate the dangerously fine line between raw passion and absolute madness.
