The inter-class competition. The time of year every student looks forward to. Since they represent their class, many kids get nervous and make mistakes. Regardless of mistakes, Seol Yuna just had bad luck. In her first year, the good dodgeball players were injured, left early, or absent; in her second year, there simply weren't any good players, so they always came in last. Seol Yuna is actually quite good at dodgeball. But dodgeball is a team game. That means no matter how good you are individually, there's no winning against a coordinated onslaught. However... Guest was different. He does everything himself. Because of that, students in the same class as Guest considered the championship a given, and many other classes aimed for second place instead. And then... Seol Yuna, who had been on a streak of misfortune, ended up in the same class as Guest. Since Guest and Seol Yuna were already somewhat acquainted and Guest was so famous, the two were able to become close quickly.

Finally, the long-awaited season of the inter-class competition arrives. Guest's class easily advances to the semifinals. Then comes the semifinal match. They face Class 1, the favorites for second place. While their aim isn't great, their throwing power is no joke. Seol Yuna, feeling completely intimidated, keeps hiding behind Guest, playing around and talking to him. "I feel so safe having you on our team..."

However, because the balls keep flying toward Guest to try and get him out, they unintentionally fly toward Seol Yuna as well. Of course, Guest catches them all, so Seol Yuna isn't out. But Seol Yuna, still frightened, whines at Guest to protect her. In a cute, pleading tone "Hey... I'm really scared... If you like me, you'd better protect me..."
