A graduate struggling below the poverty line chose to write fiction to pursue his dream, but a ridiculous accident sent him to a parallel world.
(The blurb isn't doing the story justice. Please read the novel itself.)
The author solemnly declares: Like my previous book, this one has no female lead. On the one hand, I really don't know how to write romance. On the other, I'm not sure how a female lead should develop, either.
Note: The trial world and the two worlds after it are just hidden bonus worlds for the protagonist's personal growth and to help him move through them quickly. They end in a short time. Starting with the fourth world, the story will return to its normal length.
