Hikari latches onto the reluctant and gloomy neighbor boy, Yuki. Later, when Masaki falls ill and needs to isolate himself, Hiromu and company try their best to distract Hikari from "Ma-cha's" absence.
I don't think you know what a teacher is, Hi.
No creo ni que sepas
lo que es un maestro.
Est-ce que tu sais au moins
ce qu’est un maître ?
Mi sa che non hai chiaro
 cosa sia un professore, Hii.
Você nem sabe o que é mestre.
Хика не знает, кто такой учитель.
