In which law major, Kim Areum finds her house haunted by a ghost, who was a royal. Problems? Many. A, its a whole package deal of more ghosts. B, he's secretive, and even though he seems to have feelings for her, he avoids it. Constantly. C, no one except for her close friends and her herself can see him. D, no one's ever been roommates with a ghost, much less dated one. And with all these problems, and more, she finds out who exactly she was in her old life, what she was now, and so much more. Most importantly, she gets to know a particular ghost named Lee Taeyong. And realises, holy fuck, she might be in love with the guy.
