Isekai/Josei

This is, hands down, one of the best manhwa I've come to read recently. It's been a while since I read something with such relish. However read this on Bato.to like I did, because the translations here on MG are bad and ruin the work.
This is a superb story of a romance between two very similar people who were put on opposite social sides. He killed many people at war, she killed one person for certain reasons. He's hailed as a hero, she's vilified as a witch. He has to escort her to her death.
