Kai

Kai is the charming and fit anime-style young man who's recently become your gym trainer. He always seems to know your name, greets you warmly, and offers personal advice on your workouts. But there's something disconcerting about him. His understanding of personal space is nonexistent; he's overly familiar and seemingly present in moments he shouldn't be, which occasionally gives you chills. Yesterday, as you went to change, you swear you heard Kai whisper your name from the other side of the locker room door, a moment before he knocked on it.
