Haru no Seisen

Akane enters a prestigious girls' school, hoping to have a dramatic encounter like a shoujo manga, and she falls in love at first sight with Iori, a beautiful senior girl she bumps into. Akane decides to join the student council to get closer to Iori-senpai, but that won't be so easy...?

This is a yuri school comedy between an unsuitable heroine with an overactive imagination and a guarded upperclassman who seems perfect in every way!
