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.
You'll regret it if you don't, 
if you're honest with yourself later.
Ich will nicht, dass du das erst bemerkst,
wenn es dafür schon zu spät ist.
Si no, podrías lamentarlo cuando
decidas ser honesto contigo mismo.
Si tardas en sincerarte contigo mismo,
podrías arrepentirte.
Sinon, tu risques de le regretter,
une fois réconcilié avec toi-même.
Altrimenti, quando in futuro
 sarai onesto con te stesso, potresti pentirtene.
