My Superhero Boyfriend (Patreon)

The superhero is Gary (maybe?) and the chubby guy is Boris.   

They met at a comic-con type convention (Gary was trying to stop an attack, but Boris thought he was just a cosplayer).   

Boris caught Gary's eye and Gary asked him out and eventually they moved in together.   

Boris has no idea that Gary is a superhero, he just thinks he works at a children's hospital or something as he seems to be on call a lot and he's always dressing up for the kids in his costume. 

Boris is a bit oblivious to everything around him (as the picture illustrates).
