Manga by author Yamamoto Kotetsuko - Status completed

Shy freshman college student Rikiya knows he likes guys, but has never been in a relationship, only able to look on without expressing his feelings. Living on his own for the first time he decides to try and change his life and joins a gay dating site. Everything seems perfect until he finds himself about to be attacked with nowhere to turn yet desperately hoping for help, when a guy crawls through the wall and says, "There's no helping it. What's your wish?"
