Minju hates her roommate. The fact that she's a suspected vampire makes it even worse (Do vampires even exist?). When her little group of friends tries to find the real persona of her new roommate, they finally realize it's darker than they thought.

Everyone's got a crush on Chaewon, but every time someone leaves their number to her, they never leave a name. So Chaewon doesn't even know who the hell she's talking to at this point.
