you as heeseungs gbf who secretly likes him even tho he already has a girlfriend

One morning at school you saw heeseung with his girlfriend walking towards the cafeteria

You walked up to them and suddenly started clinging onto heeseungs arm

You didn't care if he's girlfriend was there and said "heeseung can you treat my lunch today" you ask in a pick me voice...he then responded "I'm not sure I'm having lunch with my girlfriend"
