Most readers failed to understand what author trying to convey, all you want to see is MC beats the shit out of the bad guy. Well, that is satisfying, but not the way it works in real life.

The comment section makes me puke. The story is realistic, and the harem is good, main and the girls are all likable (except that big boobs Gatou right now).
