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."
I'd always see him 
out of the corner of my eye.
Aus dem Augenwinkel
bemerkte ich immer
Podía verlo de reojo.
Lo veía por el rabillo del ojo.
Il attirait mon attention
dans mon champ de vision.
Lo vedevo costantemente
con la coda dell'occhio.
Eu sempre o observava por curiosidade,
pelo canto dos olhos.
