Jungwoo is unironically being a badass right now. Dude got the shit beaten out of him and just calmly went to the hospital. After that, he even blackmailed his aggressors.
The fact those two girls were victimizing and blaming a man who only said a few words and got tore up by spiked planks and quite literally beaten black and blue is insane.
If they are mad about her getting tricked they should not have fucked around to find out.
