Lwk there so much guideverse stories, you could jst drop this one if you don’t like the MC. I feel like it being BL doesn’t change the fact he’s gonna keep acting like this considering he isekaied into a world where things like bugs and toads are 10x larger than normal. Any normal person would be grossed out by it, him being unfazed would be more mary sue. Unless his c-tier power is shown to be more helpful than just dealing with the ML’s insomnia, then he really is jst a powerless person who got summoned into a world where their norms isn’t his. From what you’re complaining about, I recommend: Mission: Save the Hunter and The Hunter wants to live quietly. To be fair, these are Mary Sues as well, but I think the plot is more well developed and has interesting characters that it’ll suit your tastes more. (Yes it is BL)

i am in mood for complaining.
so yeah if mc is a girl she will get obliterated
screaming when you see toad? screaming when you see the toad get dissected? what a city person
and he even said some stuff that sound so mary sue, um basically saying chicken soup for the soul to anyone he supposed to charm but weak everywhere else.
if it is not a bl i might drop it.
