Takao is a Shinji like MC
you hate him because he's like a real person, with serious flaws and issues
and when you have an MC like that, you get exposed to things you don't like or might be challenging to watch or think about, maybe even worse, you might see a little bit of yourself in the way they act, maybe you might even be forced to reflect on the person you are
its a type of MC that tends to filter most people, don't feel bad about it OP
