Some people complaining about the MC being annoying because he keeps complaining when he has everything when that everything literally goes against exactly what he wants because he's a hardcore shut-in neet who wants to be alone 24/7
Being a noble? He has to interact with other nobles, go to parties, make connections, administrative work, go to war, which he hates all of them (he only do the hero play for Charlotte, because he's a good lazy bro)
Noble blood=obligatory school, which he has a trauma of going to school, and he's also lazy AF so he doesn't want to
He's OP but he keeps denying it? Well, he once thought that his magic was actually 3-digits, but he saw 002 because from what he heard the most a person ever had was only in the 2-digits, so for him, the 3-digits was already a pushover, so in the 4-digits category was out of the question, he also learned how to use barrier magic by himself so he came with the conclusion that barrier magic simply doesn't waste magic at all, so rather than saying that he genuinely believes he's weak, he's more like acknowledging that he has low mana but can do incredible stuff because Barrier magic is OP, not that his mana capacity is OP, and he's also using his low mana as an excuse to not do anything
For me, this MC is way more reasonable than most other MCs who are geniuses, yet dumb as fuck, can easily get a harem but are as dense as a frickin black hole, strong but think they're actually weak (with certain exceptions)
