The new Uogokoro-kun actor Nazukari Mirai and Nanako are both first years students at the same school. However, due to Mirai's extreme shyness, they haven't become friends. Nanako talks to her friend Noda, who attended middle school with Mirai, in order to get closer to her, but her plans don't go well.

No soy tu senpai. Estamos en el mismo grado.
Mais enfin,
Não sou sua senpai, estamos no mesmo ano.
