It Was Just a Stand-in, Why are You Acting So Crazy After the Breakup?

To sum it up first: I'm being hunted by lunatics, all because I'm too dedicated. My name is Qin Fang, a transmigrator with a "Life Role-Playing System." I can play the perfect partner for my mission targets. I use my acting skills to heal one "sick" pampered princess after another. When the system's mission ends, I decisively turn around, break up, take the money, and leave. The result… all my former mission targets have gone crazy! All you goddesses out there, I just want to make money and retire! I'm a professional stand-in, I don't care about feelings, thank you! When they discover each other's existence. When they realize that the affectionate, gentle, and loyal "he" was just a persona I created specifically for them… the whole world will witness the grandest battleground ever!
