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."
He'll probably think that I broke my promise 
and told everyone his secret.
Pensará que rompí la promesa
y revelé su secreto.
Pensará que he roto la promesa
y he contado su secreto.
Probabilmente penserebbe che ho infranto
la promessa e ho raccontato il suo segreto.
