I'm not above the dirty games this boy plays.
Eunsung, pretend to suck his c*ck but bite down when he least expects it. See if he keeps that smirk on his disgusting face. If redemption is part of Jiwoo's arc, I'll only accept it with his c*ck on a plate served with tartar sauce.
Can you tell that I'm mad?
Calming down a bit, I'm not sure if Jiwoo knew about Chaeun Park when he was asking Eunsung if he was lying. Eunsung's reaction probably prompted him to investigate which got him beat up. By whom and for what reason, I have no idea. Maybe he received news of Chaeun Park, and is acting accordingly. But I wouldn't be surprise if he set up this petty revenge against Eunsung without any substantive evidence. If his investigation was actually fruitful, he would have discovered a guy stalking his boyfriend. Instead, bringing over a girl suggests to me that he suspects Eunsung of cheating.
