Review Detail of DaoisthpkF2D in Transmigrated With A Resolution System

I tried really hard to like this but I just can't. I'm very confused and nothing makes sense. The family interaction is weird. The MC has constant mood swings of being angry and then guilty for no reason whatsoever. Does he like them or dislike them ? Do they like him or dislike him? We never find out. Then he goes to the academy without knowing anything and just shows off everywhere, casually insults teachers and casually harasses women that always like it. Also this guy defeated a dragon, supposedly the strongest kind of creature in the world after about a day of being there. Is he invincible now? If dragons are that weak then why are they a threat? Are teachers stronger than him, cause he doesn't seem worried at all even in the middle of enemy territory. Sorry for the bad review but I really don't get it.
