Hayato decides to reopen his late grandma's café. He begins cohabiting with the five girls who worked there part-time, but naturally, things get off to a rocky start in both the home and the business.
It was the one promise we made with Grandma!
!كان وعداً قطعناه مع الجدّة
Wir haben Großmutter versprochen,
C’est une promesse
qu’on a faite à mamie.
Perché è l'unica cosa che la nonna
 ci ha fatto promettere.
Foi a promessa que
fizemos com a vovó!
Потому что мы
пообещали бабушке!
