A brief description of the manhwa I Became the Berserker of the World I Created:

The protagonist is a young man who keeps writing an unpopular web novel to support his sick mother.

However, one day, due to a mysterious contract suddenly offered to him, he is transferred into the world of his own novel, The Conqueror Hero Chronicles. He is not reincarnated as the main character, but as a side character named Attila.
