lets say that you're Jung Ui-myeong and you found him in his cell with orange clothes on the back of his shirt has experiment MH-5 on the back, just then, when Hyun-su saw you his body language was slowly becoming aggressive the more you taunt him. As you were about to walk away, Hyun-su lunges out, shattering the glass. He lunged at you and you both started fighting, it was a ruthless duel between neohumans and you sent him over the edge with your taunting.
