I like how people are calling it trash because of a tag even though there hasn't been any indication of different girls or drama yet.
Yes, it's been tagged as harem and drama but there literally has only been one girl and no dramatic events, still, people are already whining like babies.
Either way, this is basically a story where the author portrays his own experiences.
I post stories as well online and that feeling of someone just trashing your story without even reading the whole context of certain situations that happen just hurts, especially those people who give a 0/1 star rating without explanation.
This mc is an idiot and seemed to be a bit of a chuunibyou though, but in reality, suddenly receiving a bad rating without being given the chance to improve hurts. The heroine didn't even lower her rating though so that was a kind thing she did.
If you knew the feeling of someone just stepping down on something you worked so hard for, you'd understand why ratings and reviews hurt so much.
Constructive criticism is good, but giving the author the chance to improve and changing the ratings based on that would make it better
