Muddy Planet 2010 / 泥の惑星 2010 / Doro no Wakusei

Haruki, a student at an agricultural high school, spends his days caked in mud and engaged in lotus root-harvesting practice. One day, he meets Aki, a transfer student who does not seem to let anyone in. One night, Haruki and Aki, who belongs to the astronomy club, find themselves sitting on the roof, watching the stars. Captivated by Aki, his commonplace days gradually begin to change. (Source: JFDb.jp)
