Setoutsumi

This manga has been made into a movie and a TV drama in japan. "I wish we could just spend all our high school days sittin' and chattin' by this river." This seven chapter volume is a collection of the funky, off-the-wall, and sometimes cynical after-school conversations between Seto and Utsumi, two high-schoolers from the Kansai region of Japan.
