I will never understand why Japs are so infatuated with the "I want to be a loser, a nobody, a mob, I want to be the rug under your feet to walk on, please let me not exist!!" --trope / character trait for the MC.
It's not funny nor fun for the MC to be OP, yet keep claiming he is nothing but walking garbage. It's not charming. It's not even bare minimum writing, for every character to exist just so the MC can deny everything they are saying.
It's exactly like a harem MC to be asexual and awkward. Why even?
