When her mother remarries, she's transferred into the prestigious "Aihara Academy" for young ladies. However, on her first day at school she happens to witness the diligent student council president, Aihara Mei, making out with her hot homeroom teacher... Yuzu returns home, unable to hid how upset it left her, when her mother announces Mei will be her new step sister, and they'll be sharing a room...?!
I just transferred here today, 
so I didn't know about any of that!
Heute ist mein erster Tag hier,
das wusste ich alles nicht!
Acabo de transferirme,
así que no sabía nada de eso.
Acabo de transferirme,
así que no sabía nada de eso.

J’étais pas au courant !
Mi sono trasferita qui soltanto oggi!
Eu acabei de me transferir para cá,
não sabia de nada disso.
Я только сегодня перевелась
сюда и ничего не знала!
