Girls Beyond the Wasteland: Yume no Saki ni Shuraba wa Matsu!

Buntarou is a student who wants to be something, but doesn't know what. One day his female classmate Sayuki announces she is working on a bishoujo (pretty girl) game. Sayuki scouted him because he wrote a good script for drama club, but Buntarou doesn't know anything about bishoujo games. Source: ANN
