The question is, has Sangwoo done his research (I know I would, if I found some guy in my house), or will this be the point where he realizes just how little he knows about Bum? I mean, he did find Bum's old apartment &he seemed surprised by that, so maybe Bum at least had some ID on him when he broke into Sangwoo's place.
You know.. Bum is Sangwoo's Stalker. Of Course he can answer almost all that quetion hahaha..
