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."
Oh, I get it. Hisashi 
is searching for something.
Oh, verstehe …
Ya lo entiendo.
Está buscando algo.
Ya lo entiendo.
Está buscando algo.
Ah, d’accord.
Ah, ho capito. Hisashi vuole trovare
qualcosa da fare.
Ah, entendi...
Ну всё, теперь понятно.
