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's even weirder. 
Are you being serious right now?
Das wäre ja noch komischer.
War das grad ernst gemeint?
No lo empeores. No es tan serio.
No lo pongas peor.
¿Estás de coña o qué?
Ça serait pire !
Tu plaisantais même pas ?
Così è anche più strano. 
Ma sei serio?
Seria mais estranho.
Não faz isso de propósito?
Звучит ещё хуже!
Или ты нарочно?
ยิ่งตลกเข้าไปใหญ่
