He Qingfan, a modern female doctor, unexpectedly transmigrates to the Great Yin Dynasty. After losing her memory, she spends her days at the Imperial Medical Academy, displaying a lazy yet insightful, sharp-tongued, and independent personality.
She accidentally saves Prince Jing, Zhu Yinzhen, from an assassination attempt—a powerful, cold, and cunning man who has seen countless women, yet is utterly helpless against her. Attracted by her medical skills and unique personality, the prince aggressively pursues her, relentlessly pursuing her, determined to marry no one else.
He Qingfan adheres to the principle of "one love for one lifetime," seeing through his philandering past, repeatedly rejecting him with her sharp wit and playful banter: "Your Highness, don't rush me," driving the aloof prince to the brink of madness and utter helplessness.
Faced with palace intrigue, court conspiracies, and provocations from rivals, He Qingfan uses her modern medical skills and business acumen to slap down scheming women, resolve crises, and build her fortune. The prince, in turn, transforms from a "domineering and forceful" pursuer into a "wife-chasing marathon," showering her with excessive pampering and unwavering protection, resulting in a hilarious and sweet mutual pursuit.
From initially finding the prince too impatient, to joining hands to secure the throne and living together sweetly, she made him understand that true love is worth waiting for, and gentleness has its own power.
