Chapter 37 (final chapter) is when author communicates with us. I'm glad that author realises themselves that MC's like that annoy the hell out of people. These types of mangas are primarily created for the type of people MC is i.e. social "losers" and hikikomoris.
The sad reality is if a beautiful girl really showered them with that much attention majority of those "kind" and "good" boys would become awful people, by simple fact that they are inexperienced. It the same effect when a poor person suddenly becomes rich, they usually waste their wealth quite quickly or make catastrophic financial decisions.
With losers and love they usually become either too prideful (basically over their heads) or hurt the said girl with their inexperience and stupidity.
I don't know why i decide to finish it but i did, it was short and i saw that series ended and I decided to reat in half an hour...Yeah i cook longer than that a lot of times. Nothing more than consumer trash food, literally nothing good can be extracted from this work.
