High school students Kota and Sakura are close childhood friends who grew up like twins.
Rumored by those around them to be a perfect couple, they tried dating once, but neither developed romantic feelings for the other.
After that—
"Haha, you lost your virginity to me, didn't you?"
"Your face is all red, how cute!"
Despite being each other's firsts, they returned to being just close friends—or so they thought.
But one day, Kota learns that Sakura has won a novel award. He is surprised by this side of his childhood friend that he never knew.
Furthermore, as they solve the troubles of the school's problem child, Hagoromo, their relationship gradually begins to change...
This is an after-romance comedy depicting what happens to childhood friends who were once lovers!
