We don't know love yet.

Eiji, Naohiko and Izumi have been friends since middle school. Naohiko started going out with Izumi later on. Meanwhile, Eiji seemed to easily find his crushes one after the other, more often his seniors than not, yet maintained a laid back attitude when it came to being really serious about romance.

Now in their high school, it has been a while since Izumi has left the city and is in a long distance relationship with Naohiko. Eiji, still a single, wonders if he has been missing something in his life. Maybe it's just his poor grades but for the time being, he wants to avoid Ikezawa, his strict, serious and diligent classmate, as much as possible. Furthermore, he is aware of Taichi, a boy from a different class, who has a crush on Ikezawa.

The romantic story involving six boys and girls is about to unfold as they don't know love yet.
