Yeah I thought the same. Also I do know that singles inferno is a dating variety show for straight people but reading the title, I thought this manhwa is about a gay variety show like "his man" where the mc and ml are both gay and meet on a gay variety show called "gay's inferno" and everything but oh well I was disappointed...not only because my assumption is wrong but because the story is kind of really bad (it annoyed me at one point because of how rough ML is and how he's always making the MC cry by calling him weird/bad things only based on his assumption...)
have not read this yet but the first thing that came to my mind was that korean dating show "singles inferno" XD
