It's an isekai manga about a gamer getting transported to another world with stats that seem like trash, but are actually completely over powered. Like similar stories, he goes on an adventure to get revenge on the people who treated him poorly because of his before mentioned bad stats, but unlike some other ones, he seems like a decent human being. Furthermore, there is a very straightforward level/stats system, where a person's stats increase as their level increases, except for the protagonist. I enjoyed this manga because typically, I enjoy reading this type of story, but unless you specifically like this type of manga, it may not be your cup of tea.
