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."
Just so you know, 
all kidding aside, I'm not gay.
Damit das klar ist:
Ich mach keine halben Sachen.
Solo por si las moscas,
quiero que sepan que no soy gay.
Bromas aparte,
quiero que sepáis que no soy gay.
Je préviens,
c’est pas pour se moquer.
Solo perché sia chiaro.
Scherzi a parte, non sono gay.
Já aviso que nada de piadinhas.
Говорю сразу:
без подколов.
