The moment Ling Shuang opens her eyes, she is bound to the System: “Win over Prince Rui, Xie Yun. Reach 100% affection to go home.”
Looking at the young prince before her, dressed in fine clothes and riding a fine horse, with his nose in the air, she clenches her fist. “He's just a tsundere, right? Surely a modern office drone can handle a little temper.”
And so, the capital gains a curious sight: Ling Shuang, who has transmigrated here, spends every day circling Prince Rui's residence. He complains that the pastries she brings are too sweet, calls her jokes vulgar, and even when she pretends to be pitiful to win his sympathy, he snaps, “Get lost. You're in the way.”
Xie Yun complains about her to her face, but somehow always happens to be nearby when her half-sister gives her a hard time. When she falls from a tree while raiding a bird's nest, he just happens to catch her, then turns away with a cold expression and scolds, “You idiot. Don't get your filth on my land.”
Ling Shuang is fretting over her 60% affection rating when the System suddenly updates: “New target added: the bewitching Duke of the State, Mu Yuan. Completing this mission will also let you go home.”
Her eyes light up, and she turns straight to the duke, whose smiling peach-blossom eyes and every move exude allure. She brings him flowers, writes him poetry, and confesses beneath the moon, ten times more skillfully than she ever pursued the prince.
One day, Xie Yun catches Ling Shuang on tiptoe, feeding osmanthus cakes to Xiao Ce. The young prince clenches his fists, his ears turning scarlet, then rushes over and yanks her away. His voice trembles. “Ling Shuang! Do you want to go home that badly? Is it really so much fun... going after him?”
Ling Shuang stumbles as he pulls her away. She looks up and sees his reddened eyes, his voice harsh and strained. “Stop degrading yourself... I... I'll court you instead. All right?”
Later, the once-tsundere prince becomes the ruler of the empire.
