he basically had an illusion of bum. and i think he got hit by a car (might be suengbae's car) so most likely he did die, or if he didnt he'll kill himself to keep sangwoo's promise
oj ya i forgot about the promise. thank you
So basically bum saw a guy who he thought is sangwoo (which he isn't him) and bum ran out on the street following the guy and a truck hit him and he died
He was seeing visions of sangwoo which I think is a fitting end because sangwoo made bum promise to die after him, so bum got hit by a car and died after sangwoo
ok soo um, im cunfused about what bum, did he just go of running for sangwoo and it ended, or did he die? helpppppp meeeee
