Episode 18 recap: The prince is preparing to seize power by force.

After learning the truth, the prince is preparing to use force to take the throne. Gu Zhiyao believes that this will cause great chaos in the world, and the imperial tutor has also discovered that the mastermind behind the scenes is not the emperor. If the prince actually does this today, Gu Zhiyao is likely unable to go back and can only attack to remind the prince. However, currently, only Gu Zhiyao can launch a solo attack.

Gu Zhiyao walks alone in the palace and suddenly discovers assassins in the imperial palace. She finds the prince who is about to take action and, upon seeing Gu Zhiyao, the prince can only follow her arrangements to capture the assassins. At this moment, the emperor also comes out of the bedroom. The prince pretends to be an assassin, but the assassin takes poison and commits suicide. However, it is revealed that the assassin is from an enemy country.

Due to the prince's successful rescue, the emperor promises to reward him. Taking this opportunity, the prince proposes to marry Gu Zhiyao. The emperor, upon hearing this, thinks that the prince is lacking in ambition, and he had promised not to force Gu Zhiyao. This causes a rift between the father and son. Gu Zhiyao takes the initiative to come forward and reconcile their relationship.

The emperor bestows rewards upon the prince again, and even grants Gu Zhiyao the title of princess. After returning home, Gu Zhiyao is greeted by an excited Shen Jinmo, who embraces her. Seeing Shen Jinmo's concern, Gu Zhiyao feels reluctant to leave him and decides to create more happy memories with him before returning.
