Ookami-kun wa Yuzuranai

Usami Kuroto and Hosaki Shiro went to the same university. Seeing Shiro working hard to become a teacher, Usami was intrigued and joined the film club to find out what he wanted to do. However, Shiro is wary of Inuzuka Nao, the club's only carnivorous senior, and so he decides to come along to summer camp. While Usami is annoyed by Shiro's worrywart nature, he is bothered by Inuzuka's concern for Shiro... Also included is an overnight trip with Shishido and Shiba, and an episode about Usami and Shiro as working adults.
