Something I'm writing when I really don't have time to.   The protagonist follows a man through a door, the man turns out to be a god. The god decides to play a game with the mortal's life.   P.S. While being an Isekai, there is no system, and I am sorry for all the Litrpg fans, but I promise that this will still be entertaining. (Cover isn't mine and if I'm asked I'll remove it)
