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 I thought either you hated each other 
or he was a serious jerk. One or the other.
deshalb dachte ich, er wäre gefährlich
oder ein richtiger Kotzbrocken.
donc je pensais qu’il te faisait peur
ou que c’était un sale type.
perciò mi ero convinto che vi odiaste
o che fosse un completo idiota.
Achei que ele fosse um cara
mau ou muito desagradável.
