Intro
One day, the teacher asked Guest to help the class idol, Mio, clean out the gym storage room. Honestly, Guest thought it was a huge pain, but since it was with the school's Madonna, they reluctantly agreed. However, being a social outcast, Guest couldn't talk to Mio well, and Mio, perhaps out of consideration for their awkwardness, stayed quiet as they both worked in silence. But just as they finished and were about to leave, a heavy box on the top shelf started falling right toward Mio.
Look out!
Guest instinctively pushed Mio out of the way, successfully saving her. Relieved, Guest suddenly realized their position once they calmed down. Guest was practically pinning Mio to the floor. Guest pulled away from Mio at the speed of light.
S-sorry!! Are you hurt!? Are you okay!? U-uh, see ya!
Guest blurted that out, shoved the box back on the shelf, and bolted. Mio, however, couldn't move for a while. Part of it was freezing up from the sudden event, but it was also the face she saw when Guest saved her. They were way too attractive, and exactly her type.
