As much as we hate that Bum is slowly becoming a killer like Sangwoo (or worse) but I still hope that somehow Bum and Sangwoo aren't seperated (either one of them, OR BOTH get in jail) since it would suck that way. But judging from Bum's actions, I feel like later on he would become a killer himself and won't need Sangwoo to take care of him.
killing stalking is really a complicated comic tbh.because you can't choose between letting them live as a killer or get caught (and the series will end )
I thought he was upset that the senpai he likes and his siter are into those kind of business. Turns out he is TURNED ON also the senpai's reaction is so cute ლ(´ڡ`ლ)
