Bukatsu no Kouhai ni Semarareteimasu

Makino was always great in school and took care of everyone around him, but all of that changed when he struggled to find work and failed to make things work during his first time in bed. After the shock of it all he's been a total mess, but he finally got something to do out in the middle of nowhere. On his way there he got lost, nearly died, and hit on by another guy living in the area, Kiyomiya. Makino's got no idea how to talk to people, how to handle his emotions, or the issues he's been facing sexually, but at least where he is now, he has someone he can talk to about it all... and maybe close some distance talking about what's been going on down there...
