He knows caz he was there when they met n jisuk introduce jiwoo as his sister boyfriend
He knows. He just no longer cares for Jiyoung cuz he knows he really has no chance so he's doing it to get back at Jiwoo (like a child LMAO)
Does Jurion not know who Jisuk's older sister is??? Oh I do hope she kicks Jurion's ass for this.
