Baka de Guzu wa Daikirai

Haru has been in love with Soudai, his elder brother's best friend, since he was a child. More than his brother, Haru chases after Soudai and even gets into the same club as him. He can't be with him all the time, and if Soudai doesn't look at him, he will feel worried but he can't be honest at all.
