To be honest, after reading a number of unsuccessful stories, I did not expect anything special, but you intrigued me. First of all the colorful characters and is quite suitable for the peace of the nation. Secondly, his knowledge and skills are not taken out of thin air like many other mediocre characters. Long physical training sessions and lo and behold, he used books for information (no rebirth with knowledge of the series, gods with grand pianos, the three wishes, or the system. Real books!). Thirdly, any of his actions requires resources that he again does not take from the air, but from a specific place. Fourth, the character may have a number of survival advantages (a so-so feat considering that the surrounding teenagers are from the space station) over others, but does not stand out in front of others as Mr. Perfect and does not steal all the airtime. It intelligently blends in with the surrounding team. Fifth and no less important is the harem. Girls do not rush to the neck of the character immediately and do not spread their legs, but really gradually develop a relationship with your character. In general, a rather promising story that I want to reread and a good example to others. Good luck with your creativity, man!
