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."
You remember when we shot that promise 
video last year? What you said to me?
Weißt du noch, was du bei der Aufnahme
unseres Schwurs letztes Jahr gesagt hast?
¿Recuerdas lo que me dijiste cuando
grabamos la promesa el año pasado?

Tu te souviens de ce que tu m’as dit
avant de filmer, l’an dernier ?
Ti ricordi quando hai fatto
quella ripresa l'anno scorso?
Помнишь, кстати, что мне сказал,
когда записывали клятву в том году?
