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."
Then warm up and get some sleep. 
Put some socks on.
Wärm dich dann auf und geh schlafen.
Und zieh dir Socken an.
Entra en calor y descansa.
Ponte los calcetines.
Entra en calor y descansa.
Ponte los calcetines.
Et dors emmitouflé.
Mets des chaussettes.
Cerca di stare al caldo e dormire un po'.
E se aqueça para dormir.
Coloque uma meia.
Затем укройся с головой и спи.
Обувь только сними.
แล้วก็ห่มผ้าอุ่น ๆ นอนนะ
