Episode 13 recap: Shan Shuang Shuang left Su Yu Xuan and went to Qi Pei Ge.

Because the poisoning incident was solved, the family was very happy. Shan Dan Dan and Pei Pei also drank themselves drunk and were delighted. Unexpectedly, Pei Pei mentioned Cui Liu while drunk, and asked Cui Liu to never appear in front of them again. At that time, Shan Dan Dan was very jealous when she heard Cui Liu's name, and she went up and slapped Pei Pei, telling him to forget that name. Pei Pei was innocently caught in the crossfire and was very helpless.

Pei Pei and Shan Dan Dan walked for a long time but did not find anyone. Meanwhile, the hiding Shan Shuang Shuang was worried that they would arrive at the scene early and fall into Su Jue's trap, so she released a dizzying powder, and soon they all smelled a fragrance and started hallucinating like children.

When Pei Pei was about to kiss Shan Dan Dan, he mistook her for Cui Liu and woke up. Pei Pei quickly woke up Shan Dan Dan as well, narrowly avoiding disaster. Pei Pei felt they must have been drugged, so he quickly woke up A Liu and discussed how to proceed.

When they reached their destination, there was no one there, but they found a jade key on the ground, a craftsmanship that could only come from the Pei family. This made Pei Pei realize they had fallen into a trap, and the previous coincidences were meant to implicate the Pei family in a theft case. With the key found on them, they would have no way to defend themselves, but fortunately someone came to their rescue in secret.

After Su Jue returned home from being poisoned, the physician treated him, and although he was not in danger, there was still no better way to detoxify him. At this time, Shan Shuang Shuang rushed back and directly sucked the poison out of Su Jue's mouth, shocking Manager Wang greatly. When Su Jue woke up, he directly held Shan Shuang Shuang's hand, admitted his mistake, and explained everything he had suspected about Shan Shuang Shuang, wanting to gain her forgiveness.

However, Shan Shuang Shuang was more worried that her identity would be exposed, and for the sake of safety, she wanted to leave the Su family early and investigate at the Pei family. After returning, Pei Pei always felt that the Su family had set them up, but Shan Dan Dan felt that things were getting better and better for them day by day, and she was even happier that her sister Shan Shuang Shuang was going to help, so she told Pei Pei not to worry. However, she was very angry about Pei Pei mistaking her for Cui Liu the previous night, and she directly grabbed Pei Pei's ear and demanded an explanation, scaring Pei Pei into quickly admitting his mistake.

After Su Jue recovered from the poisoning, in order to pursue Shan Shuang Shuang, he sincerely gave her the Bi Shui Yuan Yang (Mandarin Ducks). This greatly surprised Shan Shuang Shuang, but Su Jue expressed his love for her and hoped that this opportunity would make Shan Shuang Shuang marry him. However, Shan Shuang Shuang directly rejected Su Jue.

Su Jue felt that he had not expressed his love enough, so he wanted to give all of Su Yuxuan's assets to Shan Shuang Shuang, but still failed to gain Shan Shuang Shuang's love. This time he had to go to Qi Pei Ge to reunite with his sister, which made Su Jue even more upset. Not only did Shan Shuang Shuang not accept his love, but she also had to go work for his archrival. But Shan Shuang Shuang's mind was made up, and no one could stop her.

After Shan Shuang Shuang left, Su Jue collapsed on the ground, reminiscing about how his father had criticized him for not being as good as Pei Pei, which made him hate Pei Pei even more. He wanted to demand that Pei Pei return everything he had lost. Qi Pei Ge welcomed several wealthy ladies, but they were no longer satisfied with the jewelry they had. They wanted Shan Dan Dan to help them create some more exquisite jewelry, and Shan Dan Dan agreed to their request.

At this time, A Liu excitedly ran back to report that Shan Shuang Shuang had gone there. The long-time secret admirer Shan Shuang Shuang had finally come to their house, and A Liu was naturally excited to be able to see her every day from then on. A Liu prepared a room for Shan Shuang Shuang, and Shan Dan Dan took her sister to the shop to arrange the work. Previously, Shan Shuang Shuang had worked in gold and silver jewelry making at Su Yuxuan's, so she went to Qi Pei Ge to continue that line of work. But in Shan Shuang Shuang's heart, it didn't matter what kind of work she did, as her main goal was to investigate the cause of her parents' death.

A Liu went to find Shan Dan Dan, wanting her to help him send gifts to Shan Shuang Shuang. Unexpectedly, A Liu took out a lot of money and bought a box of wild ginseng and a doll, which made Shan Dan Dan realize that A Liu was truly in love. Just then, Shan Shuang Shuang returned, and A Liu was so embarrassed that he quickly ran away. However, Shan Shuang Shuang didn't pay much attention to it, as she had no interest in love, only wanting to solve the case and find out what happened to her father.

A Liu was still daydreaming about Shan Shuang Shuang in the shop, when Shan Shuang Shuang suddenly appeared in front of him, which made A Liu extremely happy. Shan Shuang Shuang wanted to learn more about the Qi Pei Ge case from A Liu, so she had A Liu take her to the historical archives, and then she dismissed A Liu, so she could search for clues about the phoenix crown.
