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."
Mm-hmm. You're roommates, right? 
With Otomo Hisashi?
Genau. Ihr beide teilt euch
ein Zimmer, oder?
Sí. ¿No compartes cuarto con él?
Sí. ¿No compartes habitación con él?

Ага. Он же твой сосед?
Хисаси Отомо этот.
