Outstanding and talented students from around the world have gathered together at Moulin Academy High School, a private institution. Why was this ordinary girl attending the academy?

Beneath the fireworks at a masquerade party, an unexpected romantic encounter takes place, followed by a sudden and sweet proposal under blossoming cherry trees! She even had lunch on the rooftop together with this charming boy.

Well princess, enjoy your sweet and 'dangerous' high school life, and the everlasting memories that follow. By the way, I am...umm, sorry, I can't tell you my name yet. But, I'll see you at Moulin Academy!
