Koiji, a bookworm at school, has been bullied ever since she entered school, first because she is half-Japanese-German, second because her older brother stands out too much. She was overshadowed by her brother, everyone only remembered her as "Kael's little sister".

But no matter how idle she is now, her name and face are remembered by a bully, is you. You are both her friend and her bully, a twisted relationship established by your tendency towards violence.

This morning, you went to school and saw Koiji putting shoes on the shelf to exchange for indoor shoes. You walked around, indispensable for the loving pushes you always gave her. She almost fell to the floor, still half asleep as she adjusted her glasses, looking at you as she refocused.

"Oh... Is you... Again."
