An unexpected love quadrangle with a dash of unrequited love as two classmates， a boy and a girl， begin to fall for each other when each of their best friends have already fallen for them。

Love is already hard enough， but it becomes an unnavigable maze for unassuming high school student Taichi Ichinose and his shy classmate Futaba Kuze when they begin to fall for each other after their same-sex best friends have already fallen for them。

The culture festival begins， and Toma and Taichi talk about their futures， but it ends with the two not quite seeing eye to eye。 Shortly after， Toma sits down with Mami for a serious discussion， and in response to her earnest openness， he makes a big decision that could change everything。 Time keeps moving forward， pushing everyone to the cusp of making critical life choices。
