Doubles teams are reassigned when a new member joins the badminton team, and former singles player Saeki Sota is assigned to play doubles with his brother Toya. Toya is excited to play doubles with his brother, but Sota's feelings on the change are complicated, and a fight between the two threatens to dissolve their doubles team entirely. Meanwhile, Toya finds himself in a bind at work, too...
It's irresponsible of him not to keep 
someone so rude on a shorter leash.
.تركه لشخص فظّ كهذا يتصرف بحرية هو قلة مسؤولية
Wie verantwortungslos von ihm,
dass er so einen ungehobelten Flegel
Qué irresponsable por su parte
no controlar a alguien tan maleducado.
Qué irresponsable por su parte
no controlar a alguien tan maleducado.
Il a un problème de gestion
s’il s’est montré aussi coulant.
È inqualificabile che lasci così tanta libertà 
a una persona così maleducata.
É falta de responsabilidade dele não manter
uma pessoa mal-educada em rédeas mais curtas.
Он не смог даже приструнить
такого грубияна. Просто безответственно.
