This show in a word is amazing. The story is about a shut in, who had literally given up was given a second chance in life through reincarnation while having many flaws at the beginning. Our main character sets off on journeys, slowly fixing those flaws while interacting with the surroundings and facing many challenges. Yes, you will not like the protagonist at the beginning but later on he becomes someone you like. He isn't someone whom you would relate to since the beginning. If you're thinking whether you should watching or not, definitely give it a try. In my opinion it is the best isekai I've seen so far.
