In the dormitory of an all-boys school, Mao ends up sharing a room with Hisashi. They make three promises to each other: "Mao won't disclose that Hisashi is gay and has a boyfriend," "Kotobuki won't see Mao as a romantic interest and won't make a move on him," and "they won't interfere with each other's private activities."
But no matter what happens later, I want you 
to always remember what we did here.
Was auch passieren wird – ich will,
dass ihr euch später daran erinnert,
Pero pase lo que pase, quiero que
recuerden lo que hicimos aquí.
Pase lo que pase, quiero que
recordéis lo que hicimos aquí.
Quoi qu’on devienne,
je veux qu’on repense à ce film.
Ma a prescindere da ciò che accadrà in futuro,
Não importa como seja, quero que
se lembrem disto lá na frente,
Короче, как бы мы там ни жили,
хочется, чтобы про фильм не забывали.
