OK so I read the novel to some extent first then came for the webtoon version, the novel's way better than this. somehow felt there was irregullations in the events or there was some shortcomings in steaking them together so I liked the novel better :) , but it's still a good quality read, I love mc hope he gets his goal achieved ha ha
