Nasa Yuzaki is determined to leave his name in the history books. Ranking first in the national mock exam and aiming for a distinguished high school, he is certain that he has his whole life mapped out. However, fate is a fickle mistress. On his way home one snowy evening, Nasa's eyes fall upon a peerless beauty across the street. Bewitched, Nasa tries to approach her—only to get blindsided by an oncoming truck. Thankfully, his life is spared due to the girl's swift action. Bleeding by the side of an ambulance, he watches as the girl walks away under the moonlight—reminiscent of Princess Kaguya leaving for the moon. Refusing to let this chance meeting end, he forces his crippled body to chase after her and asks her out. Surprised by his foolhardiness and pure resolve, the girl accepts his confession under a single condition: they can only be together if he marries her!

Due to her unusual powers, Qian Yun Xi was exiled by her family when she was a child. Deprived of filial affection, she made a life of her own amid the wilderness on Mt. Ling Yun. However, everything begins to change when she marries Ye Youming in her sister's stead. Harboring immense contempt for the family of Qian, Ye Youming refuses to acknowledge Qian Yun Xi as his wife and treats her coldly, going so far as to banish her from his palace grounds. But he can only resist her childlike charm and boldness for so long...
