Bob's your uncle

I don't think he actually lived with his uncle. Maybe in the past but not anymore. Bum hasn't taken the best care of himself, health wise or in general cleanliness, so he proably lived alone. Completely speculating, but I think that his uncle finanically supported Bum in return for sex. When Bum went missing his uncle would have stopped sending the rent. I didn't get the impression his uncle cared for his well being so he might not care that Bum is missing.

I think the nail polish and other items were stolen from people he obsessed over. There's a theory that Bum dressed as a woman to stalk people but I can't imagine him successfully cross dressing.

Thanks. That makes sense. It's hard to tell because when we see things from Bum's POV, you can't trust what is "real' completely. Not that you can trust anyone in this story.

I think Bum has a place of his own and maybe a place at his uncle? In chapter 1 we see him in this bed: http://www.mangago.me/read-manga/killing_stalking/mf/c001/35/ and this one http://www.mangago.me/read-manga/killing_stalking/mf/c001/15/

The first one is clearly not the same bed as his apartment so I'm guessing it's the one at his uncle since it's more furnished than just a mattress on the ground.

I'm not sure if his uncle financially supported him in terms of rent since the landlady said bum being a student and not having a job was not an excuse to pay rent...the way she said it made it seemed like she spoke with bum about missing rent prior to Sangwoo.

I noticed the two beds too--it's one reason I was wondering where we were in Bum's mind at the time. I also saw that Sangwoo calls Bum "middle-aged" (in English anyway) when he can't possible be over 30. He may be an older student, but he should be about four years older than Sangwoo, right? Sangwoo can still pass for 20, and skinny little Bum shouldn't look that old to most people. So sometimes I wonder.

I think the furnished bed was when he encountered Sangwoo again after the army and started his stalking him. Koreans add a year to their age so Bum was 23 when he first met Sangwoo in college (since he started 4 years late), 25 by the time he finished his army service, and assuming a year has passed, I want to say he is 26. The reason for that is the police mentioned Sangwoos parents being murdered 3 years ago when he was in high school...assuming it's the end of high school/early start of college + 2 years of army service...seems right that only a year has passed at most.

There's a theory that Bums uncle pays him for sex. One day Bum will have sex with him in his house the next at his that's why you see two different places.

Yeah, I've seen that mentioned a few times but not sure I buy into it quite yet...

There's really not enough information to be fully convinced on anything about Bum's uncle. I thought the money for sex theory makes sense because Bum hasn't been shown to have a job and it could explain how Bum got money. The condition of his apartment makes it appear that he lived alone. However based upon what Bum said and his flashbacks about his uncle I believe his uncle came to him for sex on a regular basis. If Bum lived alone without assistance from his uncle then why would going back mean him seeing his uncle? I figured he could lock himself in his apartment to escape his uncle otherwise.
