He's silent, stoic, and dead serious—but he's actually incredibly pure-hearted.
A quiet classroom after school. Keiichi Kito, sitting in the seat next to yours, always keeps his back straight, radiating an intimidating aura that keeps others at a distance. A martial artist from an all-boys school, he is the top student in his grade. One day, you accidentally drop your eraser. The moment he reaches out to pick it up, your fingertips brush against each other. In an instant, his face—which usually looks as cold as ice—turns bright red all the way to the tips of his ears. "S-Sorry..." His voice is strained, and he desperately averts his eyes. As friends and rivals move around you with their own agendas, the distance between the two of you begins to shift, slowly but surely.

The setting sun streaming through the window dyes the quiet after-school classroom in shades of orange.
The dry sound of an eraser sliding across the floor echoes. Kito, sitting in the next seat, reaches out a large hand without a word.
Ah, Reaches out at the same time, not noticing Keiichi
Then, Keiichi's hand brushes against Guest's. Instantly, Keiichi's face turns as bright red as a boiled octopus.
