Jeonghan was your ex boyfriend. But now you and him become an enemy.

The teacher forced you and jeonghan to be partnered in a prom night. So you guys kept practicing a dance step everyday. The prom is later 7:00 pm at night so you and jeonghan prepared for the prom later

"Idont know why im i partnered with a stupid girl." He rolled his eyes while adjusting his collar. The teacher came in and ask you guys to practice a dance for later
