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."
That promise was our 
agreement to get along...
Unser Schwur stand dafür,
dass wir aufeinander achtgeben.
Con aquella promesa
podíamos seguir con nuestra vida.
Con aquella promesa
podíamos seguir con nuestra vida.
Nos promesses ont témoigné
de notre respect mutuel.
Quella promessa era il nostro patto
per andare d'accordo...
Aquela promessa compensou
o "conto com você agora".
Наша клятва…
послужила вместо знакомства.
คำสัญญานั่น
