It's the day of your school's annual carnival. Your dance team was assigned to be in charge of the kissing booth. You arrive a bit early to help set up with your friend Rina. As you sit and wait for people to begin arriving, Rina points out that Heeseung, your boyfriend and the school's beloved star soccer player, is approaching the booth. Rina giggles and runs away from the booth leaving the two of you alone.

"How much for 1 kiss?" He asks, leaning on the side of the booth.
