In the king's interrogation room, Si Zuxian handled Guier's case in an unexpected way.He did not refute Chen Wuda's accusations, even though they were made to save the woman who was forced to lie in court.

He frankly admitted that he had asked Guier to wear the assassin costume he specially made for her.They met before the king's banquet and were in love.On the night of the banquet, Si Zuxian mistakenly thought that the woman chosen by the king was Gui'er, so he hurriedly found the king and asked to marry her.Guier's testimony supported Si Zuxian's statement that her body remembered the draw and dance, even though her mind had forgotten it.

Si Zulong became suspicious of Gui'er's motives when she admitted her relationship with the prince.The concubine's canonization ceremony continued, and Gui'er began to slowly fall in love with the palace and the prince.She learned from Hong Jun that her favorite flowers were also the crown prince's favorites, so she picked some as gifts.

On the way home, Gui'er encounters Si Zulong and her childhood guard Yang Zaiyi.However, she showed no emotion, leading Si Zulong to conclude that she had lost her memory.Si Zulong proposed to temporarily cut off contact until the memory was restored.

Meanwhile, Si Zuxian wants to know who framed Guier.Princess Jinhua appears before the king and reveals that the dancer has perjured herself in court.She was jealous that the prince chose Guier, so she ordered the girl to be punished.The king expressed his appreciation for the crown princess.

The king is furious to discover that his pursuers are now after Concubine Eunhyo, who may become the new dynasty's queen.When it comes to Guier becoming queen, Jinhua's reaction is full of dissatisfaction and anger.

Later, Jinhua and her father tell the same story to the crown prince, accusing the dancer of lying out of jealousy.However, the prince is not as easily fooled as they thought.Ergui has already changed the situation and brought the dancer who took the blame for Guier to the detention center.

Sizulong has a strong desire for the throne and asks why his mother fell into Jinhua's trap.On the other hand, when Si Zuxian was practicing archery at the archery range, he kept thinking about why Gui'er kept lingering in his mind.He suspected that she had seduced Ergui in order to become his concubine, and thought she was faking amnesia.

Gui Er came to the archery range to thank him for his help in court, but Si Zuxian said that he did not do it for her, but for the stability of the palace.He told Guier that she should not appear in front of him again.

Si Zuxian ordered Guier not to enter his house, but she sneaked in and gave him the dye she made.When she heard him enter the room, she ducked under the table.After Si Zuxian discovers her, his memory returns to the most painful moment in his life, when his father forced him to witness the massacre during the coup.

The look in Guier's eyes reminded Si Zuxian of the little girl he had saved. However, he still couldn't let go of all the trouble she caused him later.Holding the sword in his hand, Si Zuxian once wanted to kill Guier, but was finally stopped by Ergui taking over his body, thus saving Guier.

Guier witnessed the fierce struggle between the dual personalities of Si Zuxian and Ergui. She felt that the temperature around her was hot and cold, and Si Zuxian's eyes seemed to be constantly changing colors.In the end, Ergui defeated Si Zuxian, but after waking up, he behaved extremely coldly towards Guier and even ordered her to leave.Guier couldn't help but began to wonder whether the prince in front of her had really become so strange.

The anger in Ergui's heart was burning, and he became even more angry when he saw the dye that Guier carefully made for him and the letter thanking him for saving him in court.Because she still had deep feelings for Si Zuxian, which he couldn't accept.His nervousness reaches its peak when he learns from the letter that Gui'er will leave that night because Si Zuxian has allowed her freedom.

Subsequently, Ergui made two decisions.He first threw Chi Quanshu into prison, while Neng Neiguan was demoted to a laundryman for drugging him and forcing him to sleep.Then, he began to plan how to make Guier hate Si Zuxian.He told Guier a story about his body being possessed by an evil spirit, but deliberately distorted the facts to describe Si Zuxian as the evil spirit.Although Guier expressed doubts about this, this statement still seemed to change her attitude towards Si Zuxian to a certain extent.

Ergui reveals to Gui'er that he has found a way to get rid of the evil spirit, but it requires Gui'er's help.Guier agreed to his request after hesitation.On Guier's way back to her room, Ergui suddenly appeared in front of her and warned her that someone wanted to harm her.He tried to convince Gui'er to leave with him, but Gui'er refused to trust anyone anymore.

Hong Jun stopped Gui Er before she left and gave her some items.Among them, Guier found a dagger and a note.The note said the dagger would come in handy when she regained her memory.Guier's heart was filled with doubts and expectations.

At the same time, Ergui is plotting against Si Zuxian.He plans to get rid of Si Zuxian and take over his body, thus having the power to become the crown prince.The next morning, Guier dressed up as a servant and met Neng Naiguan by the river.Neng Naiguan has noticed that Ergui has revealed things about his dual personality to Guier.

However, Neng Naiguan deliberately reversed the truth and told Gui'er that Ergui was the real prince and Sizuxian was the evil spirit.This made Gui'er even more confused. She didn't know who to believe. Gui'er fell into deep thinking.
