Hmm

Ngl I wish the mc was the sword guy. I thought this was a unique webtoon since we get to find out the story of a hero who came back to his original world and became the villain. We don't get much villain mcs in manhwas where the villain is actually a villain and not just some random person who possessed a villain in some story, because they either possessed the villain or gets transferred to another world and named the villain of the story, what they usually do is deny the fact that they're the villain and try to be a good person. Maybe what I'm looking for is something new whereas we get follow the villain's path to world demise and throwing the society upside down for turning him/her like that. Anyways that's just my opinion, if you like the current mc sure I got no problem with that.
