The first 3/4 are perfect. The show explores fantastically the cliche scenarios para only happen in BLs time and time again. I love the fact that our protagonist is such an extra that he doesn't even have a name, he's just Mob. The fact that he's the only one aware that this is a BL world makes everything funnier.

I don’t hate the ending. It makes sense for the protagonist to end up falling for a guy. But it would have been so nice to actually see him escaping all the tropes and be alone in the end, judging everybody around him. Or at least have him fall for a guy without it being connected to super cliche, like what ended up happening.
