Housemate from Hell

Rigid and blunt college student Kwon Jeongha can't stand Gwak Hyeonwu, a handsome, popular classmate who casually toyed with the senior Jeongha secretly loved. The two clash every time they meet... until Jeongha picks up a mysterious necklace and their relationship flips overnight. Claiming he's a demon, Hyeonwu reveals that all the magic he'd stored in the necklace has been absorbed by Jeongha. To make matters worse, Jeongha will die unless it's returned. But the only way to transfer the magic back? Physical contact. Forced into an uneasy cohabitation with a demon he despises, Jeongha's quiet life quickly descends into chaos.
