Unlocking a Cozy Captivity

Sunwoo attends his university's end-of-semester assembly. Trying to shake off the alcohol, he steps outside for some air. While he's out, Choi Ihyeon, a well-known figure, offers him a drink. Sunwoo takes it and promptly loses consciousness.

Ihyeon then confines the now-conscious Sunwoo in his home, forcing him to live there. Despite being held captive, the life is surprisingly gentle and comfortable, triggering memories from Sunwoo's childhood.

"Do you finally remember what you did to me, Hyung?"

"I don't need pocket change; pay me back with your body."

This is Sunwoo's imperial confinement journal, his journey to save Ihyeon, who is bound by trauma!
