Koxia (Sano Reo), Matsu (Nakagawa Daishi), Tsukichika (Takasugi Mahiro) and Hui-chan (Yokohama Ryusei) are high school classmates. Although they have different personalities, they have a very good relationship with each other. Koxia fell in love with a girl named Anna (Kobayakawa Anna) in the class. He told his brothers about his immature unrequited love. The other three actively gave him advice, but they made jokes repeatedly. In the process, Matsu fell in love with Anna's friend Jasmine (Tsunematsu Yuri), but Jasmine is a girl who hates male creatures very much, which makes Matsu very distressed. At the same time, Tsukichika is about to start a long-distance relationship with his long-time lover Yukimiya (Horita Mayu), and the insecurity deeply affects the relationship between the two.
