Despite her gyaru looks, Aihara Yuzu is an innocent high school girl with no experience and no prior loves. 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 and 
didn't know the rules,
Ich bin an diese Schule gewechselt
und wusste davon nichts,
Acabo de transferirme
y no sabía nada de esto,
Acabo de transferirme
y no sabía nada de esto,
Tu dis qu’on est toutes pareilles,
Mi sono appena trasferita qui, 
non ne sapevo un fico secco di 'ste cose!
Eu vim para cá e não sabia de nada disso,
Я только что перевелась и ничего знала,
