Wow, the MC has no sense of self-worth whatsoever but the story is still glazing it to high heaven. Being generic is a thing, but maybe it's just me but I can't stand this kind of pushover-ness from any character, let alone an MC. The exact same reason why I can't stand Liu Bei in Three Kingdoms.
And everyone around him treating him poorly is the result of the combination of him just shutting up and people being absolutely stupid.
