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 bet she's lived a boring life, 
with no time for love.
Die hat bestimmt kaum Freizeit
und führt ein total ödes Leben.
De seguro ha tenido una vida aburrida,
sin tiempo para el amor.
Seguro que ha tenido una vida aburrida,
sin tiempo para el amor.
Elle peut même pas se faire de copain…
Paie ton adolescence.
Dev'essere una palla, senza nemmeno 
avere la libertà di innamorarsi.
Aposto que ela vive uma vida sem graça,
sem tempo para amor.
Небось у неё нет времени
даже на любовь. Какая скучная жизнь.
