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 just smiles a little 
and says, "Nah, I'm good."
se limitaba a sonreír y negarse.
se limitaba a sonreír y a pasar.
il refuse avec un léger sourire.
lui risponde con un sorriso
 e un "No, sono a posto così".
Mas apenas dá um sorriso
dizendo "eu passo".
он только отказывался и улыбался.
