Sano Koudai

Masaharu's friend and classmate with Chisa, Rie and Yuuki. He is also looking for a girlfriend but he is not as popular as he thinks and there are almost no girls speaking to him to become his friend, only Yuuki and Rie speak friendly to him but they do not see him as a potential romantic interest.

From his unpopularity was born an immense jealousy against Masaharu who, in addition to having a beautiful childhood friend, is surrounded by pretty girls like Chisa, the president of the student council or the pretty little Kouhai named Sumire.
