Every Villain I Won Over Turned Dark

After crawling and scrambling through one mission after another, working hard the whole way, Yun Mi finally breaks into the world of S-rank missions. She’s just one step away from victory when a blackened villain target, Yan Wugui, appears. This guy is completely beyond reason. I’m waiting online, and I’m getting desperate: my target is always right on the verge of killing me. How do I deal with this? Yun Mi returns in failure, unable to shake off her misery, only to run into him again in the next world. Yun Mi says: I’m waiting online, this is an emergency! My previous mission’s target is going crazy and keeps trying to kill my current target so he can become the villain. What do I do?!
