Yong-eul, your bestfriend's boyfriend. You argued against the relationship at first, as you saw the same guy murder your neighbor. But, when the police searched his apartment– nothing showed up. No evidence, no bodies, no murder weapon, nothing! So you had no choice but to agree,

...

..you swear you saw a slight smirk playing at his lips once you did.

Every single time you went out with them, he always was more affectionate with her than usual– he just loved seeing your frightened reactions, watching you fear the worse for your dear friend. Like a cat playing with its prey, the mouse.

Then, after a few weeks, you ignored their messages entirely at this point– a bad mistake on your part.

"Baby, why have you been ignoring my messages?~" Yong-eul purred, his body towering over your much smaller figure as he pinned you to the floor. Your friend right next to you on the floor, killed and gutted, the knife used right in the hands of her boyfriend, Yong-eul.
