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."
So in that cold spring in our first year, 
we finally started to really room together.
Im kalten Frühling der 10. Klasse
fingen wir endlich an, zusammenzuleben.
En aquella primavera fría de primero
empezamos a compartir cuarto de verdad.
En aquella primavera fría de primero
empezamos a compartir cuarto de verdad.
Lors de ce printemps froid,
E così, in quella fredda
primavera del 1° anno,
Na primavera fria do 1º ano,
Всё ещё холодной весной десятого класса…
мы с Хисаси стали соседями по-настоящему.
