Yana,20 y.o, is a man who really questions about the world's system.
why do you praise a genius? a prodigy?
why are you ignoring a hard worker?
An obvious result by a genius is more attractive than a barely visible result by a hard worker. He can't understand that.
He lives his life by helping a hard working person until one day, an existence that is called "god" appears before him and ask his help to win his "game" in another world.
