I don't think bum did anything bad to sangwoo here. I feel like he kept looking in the medicine box for the rat poison to sadly reminisce and get lost in the past on how he almost killed sangwoo with it. and that he WOULDNT want to now. the lost pill was probably when he dropped them and one rolled away. but im not sure. the story's been screwed up all throughout so maybe bum is really trying to kill him. would be quite the sick twist. or sangwoos gonna kill bum and find the missing pill after the fact. if this ends in any other way than a murder suicide id be very shocked at this point.
