Boku no Hajimete Gay Konkatsu

This is an autobiographical story about the hard-core otaku Hiroki Iida's search for a gay marriage partner, adapted into essay comic form by Harekawa Sinta.
"I just want to find someone that's right for me," that was Hiroki's goal when he got into "matchmaking." As he meets all sorts of different men, he himself will grow as a person, too.
