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."
Because it's going to 
hurt Hisashi's feelings.
Ich will Hisashi nicht verletzen …
Porque heriría sus sentimientos.
Porque le va a herir sus sentimientos.
Je veux pas lui faire de mal.
Perché ferirei i sentimenti di Hisashi, no?
Pode ser que deixe o Hisashi magoado...
А я не хочу обижать Хисаси.
เพราะคิดว่า
อาจจะทำให้ฮิซาชิรู้สึกแย่
