Spoilers
Based on a summary in Tumblr (scroll down, someone else posted a link)
The girl was the only person who had ever talked to Bum as a kid--and she revealed to him that she was bruised because her dad was beating and raping her. They had a kind of friendship until one day the bruises were gone, and she started to pull away from him. It seems her mom divorced her dad, and she lives with her mom. Now that she can be normal, she likes someone else and wants to leave Bum behind. I think Bum starts stalking her as she tries to blow him off. He steals her nail polish and leaves her letters. Finally, he confronts her and they blow up in class and she yells at him and says nasty things...things similar (or close enough) to what Bitchy Miss Cannon Fodder (sorry to those who like her) was saying.
That's when Bum proceeds to get stabby. He is shouting at the first-love-gone-bad as he kills. Sangwoo is happy.
I wonder if Sangwoo researched Bum's past or if he just guessed a girl like this had once chosen a hot guy like him over Bum? Do all the girls look like Sangwoo's mom, or is it just the artist's style? Should I keep looking for a mole on the face?
So i just saw chp 19....

Bum looked really well put and clean in the flashback. Was the brown haired girl (the girl he supposedly stalked) and him in some sort of secret relationship that turned sour?
P.s. omg he did it! He actually DId it!!!!! Omggggg
