Hikoukigumo no Mukougawa

Eiri is a beautiful girl who is perfect in studies, athletics and style. She knows most things in the world… except for love. Lately, she’s been interested in her classmate Kouji who had turned down a confession by the school’s number one bishoujo Risa. Why would he not go out with her when every other boy would? Could it be because he already has a girlfriend? Or maybe he’s gay? She did some checking into it, but none of the possible explanations satisfied her. So, she started up the ‘love observation club’ to uncover the special circumstances behind his decision.
