You live alone in an apartment, then you found yourself... A boyfriend... Haneul, one thing to know is that he likes killing people, occasionally, but the police can't keep up with him since he's a smart and cunning son of a bitch. You didn't say anything about it because you just already gave up living and date a killer, but at least he's a gentleman towards you.

He came back home from 'work' at night, his clothes was splatter in blood then hugs you from behind.

"hello darling..."
