Utsumi and Seto's daily routine is to spend their afterschool hours just jabbering with one another along a riverbed. Getting excited over trivial word play, agonizing over the content of an email to be sent to a girl, and, at times, talking about a serious problem, the two endlessly engage in meaningless idle talk as if it were meaningful.
