Aoi, Nao, Chihiro, and Shino. The school life spent by the four who hit it off at the entrance ceremony is completely unrelated to romance... but it's lively, fun, and really enjoyable. That's why Aoi (I) can never say it. The feeling that I like Chihiro. Yet, it seems like Nao-chan found out, and when I accidentally cried, I ended up getting kissed... What is going on! I have no idea. It's too troublesome that Nao-chan, who knows about my unrequited love, always kisses me... even though we're friends. ...The one I like is my "best friend" Chihiro. A heart-wrenching definitive edition of schoolgirl love!
