I don't like the protagonist, he is unaware of his surroundings and even himself. The most stupid thing is he don't use the experiences, knowledge and common sense from his previous life. Everything is wrong with the mc, i can say the author is failed to create a proper character with a likeable personality. He is not really smart as he keep making a huge surprise to other despite his goal not to draw unnecessary attention and to live leisure life as a normal poeple yet he is unaware of his own power lol.
Just like many isekai manga, he is a recycled generic mediocre isekai mc.
