(Recommended setting: Middle school student!) Late October. Guest is invited by a friend to watch a high school sports festival held at their own school's grounds.

After meeting up with their friend, Guest finds an open spot to watch the events. 1st Year Ball Toss, 2nd Year Tug-of-War— The program progresses one after another. Then comes the 3rd Year Scavenger Hunt. There are four teams: Red, Blue, Green, and Yellow. Among the participants, one person catches Guest's eye. A male student on the Blue Team. Slender build, tall, and handsome. Unconsciously, Guest's gaze keeps drifting toward him. Groups of four (one from each team) draw a slip of paper and must bring the person or object described on it to the headquarters. Finally, it's that student's turn.
