Good Night Neighbor

Synopsis

Yeoh-eul despises thugs and womanizers, but her next-door neighbor, Un-gyeol, seems to be both. Plagued by excess yin energy that attracts dangerous spirits, Un-gyeol needs a woman's yang energy to save him. Realizing Yeoh-eul is the one who can solve his supernatural problem, he initiates a passionate physical relationship. While Yeoh-eul tries to keep their relationship casual, fearing he is a deceitful, rotten playboy, Un-gyeol grows deeply, obsessively devoted. Is this fling bound for a friendly ending? Or will Un-Gyeol not allow it to end at all?
