From Aerandria Scans:

Rinko is a girl who goes to a female-only class with fancy facilities, established in a formerly boys-only school. The nickname of her class is "the girls' class." Even though she's treated as a VIP, associating with guys is strictly forbidden, so every day is very boring for her.

On top of that, she is one-sidedly in love with her childhood friend, Kousei, who also goes to the same school. But attending the same school is wasted, as long as the rules say she can't talk with the male students! With him with the help of a friend she recently made, Shuu, Rinko sets out on a quest to reform the school!!
