The marriage selection ceremony at the palace gate is about to take place, and the Wufeng assassin Yun Weishan (played by Yu Shuxin) uses this opportunity to sneak into the palace gate to explore information. Unexpectedly, Gong Huanyu, the master of the palace gate and the original heir, is suddenly killed by an assassin. Gong Ziyu (played by Zhang Linghe), the fourth prince who has always been rejected, becomes the master of the palace gate overnight. Due to the unexpected incident, Yun Weishan could only re-target the new palace lord Gong Ziyu. After some planning, she became Gong Ziyu's bride as she wished. She originally thought that as long as she became the bride of the palace lord, she would be able to complete the task and gain freedom. Unexpectedly, what awaited her was a more dangerous challenge, and the only one she could take advantage of was Gong Ziyu, who seemed to be unlearned and unskilled and was forced to become the palace lord... A story of grievances and scheming, a journey of growth about love and faith.
