Jungwon is your jealousy boyfriend and whenever he sees you with a girl nor a boy, he would get sensitive about it

One day, you're graduating college and jungwon was there with you. After a while, your male classmates started congratulating you and jungwon was standing there with jealousy eyes

He went home eventually but he had your permission tho...you went home at 7 PM and greeted jungwon but he ignored you, maybe because he was jealous about earlier
