DOES SANGWOO LIKES BUM SOMEHOW BUT JUST SHOWS IT IN A BIZZARE WAY OR HES JUST REALLY FUCKED UP?

Sangwoo likes bum

and fucked up at the same time, I think it's more like obsession instead of a healthy kind of love.

It's not like. It's just attraction due to serious mental illnesses

It's as close as Sangwoo can get to love, being as he is really fucked up. Sangwoo has created an image for Bum in his mind, and a role for Bum in his life. They share their darkest and sickest moments--an intimacy no one else could have. To Sangwoo, this is probably how he think love is. It may be how Bum thinks love is too, because up till now, love has always meant pain and obsession. So, they have complex codependent feelings that are very intense and focused on each other. But don't expect rainbows or ponies to appear.
HEHEHE
