MTL - Time is slow - Chapter 785 rattling swords

Kenji’s life was hard. During the day, he worked in a bookstore. At night, he served ramen. He did it all to take care of his family. His mom was sick and needed medicine, and his little sister needed money for school. His best-paying gig was working for a mysterious author, illustrating the manga for a popular web novel. There was just one problem: he hated the story.He was in the middle of drawing the academy arc when his frustration peaked. The story’s villain, a rich kid named Azrael Ashveil, was weak.

Looking in the mirror he sees the handsome, violet-eyed face of Azrael Ashveil. He has entered the story he hated and is now the doomed villain.Worse, he's arrived late to the party. The original Azrael has already made a mess of things. The story's golden-boy hero, Kaelen, already despises him. His beautiful wife, the half-elf heroine Elvara, is terrified of him. And all of his death flags-the events that lead to his execution are right around the corner.Azrael must use his knowledge of the future just to stay alive. Can a minor villain with no power of his own really change his fate, or will he just find a new, even more tragic ending than the one he was trying to escape?
