Lin Ye, a tough modern-day guy who does two hundred push-ups a day, stays up all night battling through games to defeat the final boss, opens his eyes to find he's transmigrated into ancient times as Su Qingdai, a frail maid doomed to be a disposable extra.
Flat-chested and skinny-legged, ready to topple in the wind? The System forcibly binds him to a villain-reform KPI. His target is Xie Linyuan, the seventh prince, feared throughout the capital for his murderous rampages. Fail the mission, and he'll explode on the spot!
From then on, Prince Su's manor goes completely off the rails:
Xie Linyuan raises his blade to kill someone, but she grabs his wrist. “Swinging weapons this early in the morning is bad luck. Come on, three sets of high knees first!”
She finds the dried plums he's hidden under his pillow for three years. Munching on one, she complains, “They're this far past their expiration date and you're still eating them? You'll be on the toilet all day!”
When a noblewoman at the palace banquet flirts with him, she shoves a skewer of candied hawthorns into his arms. “Stop acting so aloof. Your eyes are practically glued to the candy!”
The once-fierce, unhinged prince is completely baffled by this “maid” who makes him jog every morning, steals his snacks, and swings a broom at his imperial elder brother.
What happened to timid and cowardly, easy to push around? She fights more like a villain than he does!
Even worse, the way he looks at her is sweeter than the candied fruit he keeps hidden.
The System blares out warnings: [Warning! The villain's favorability is skyrocketing! The reform mission is straying from the goal of turning him into a model citizen!]
Su Qingdai (with Lin Ye at the core): “…How about we fatten him up by ten pounds first? That should make him easier to reform.”
Xie Linyuan (quietly taking out the hairpin he just bought): “How about we change today's morning run to a walk together?”
