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."
He sure gets stubborn sometimes. 
Only thinks about himself.
Bei so was ist er nicht zu stoppen.
Dann gibt er den Ton an.
Qué terco puede ser…
Solo piensa en sí mismo.
Qué cabezón es a veces…
Solo piensa en sí mismo.
Quand il a une idée dans la tête,
il réfléchit pas plus loin.
A volte si fissa proprio.
Quando ele fica assim
ninguém o faz mudar de ideia.
Вот попробуй его переубеди теперь…
Он же упрямый как осёл.
เห็นแบบนั้นหัวแข็งไม่เบาเลยนะ
