Zhou Dantai was leading the party, and a banner suddenly hung down outside the glass. On the banner was the words that the murderer of Xue Ya was among the people at the party. The person hanging the banner also hung a dummy to represent Xue Ya.
Zhou Dantai proposed to end the party, but Gu Hucheng disagreed, expressing intentionally that he wanted to see if the event would be fun next. Qian Ruizhen suspects Shen Xiulian and believes that Shen Xiulian killed Xue Ya. Gu Hucheng left the party site and used the surveillance camera to check the scene of Zhou Dantai and his party at the party site. Qian Ruizhen pretended to be threatening and determined that Shen Xiulian was the murderer.
Shen Xiulian received a message from Gu Hucheng. Gu Hucheng threatened Shen Xiulian and asked Shen Xiulian to declare that she was Xue Ya's biological mother. He gave Shen Xiulian a minute to think. Shen Xiulian was in a dilemma, and did not announce her own details according to Gu Hucheng's request.
Shen Xiulian investigates Gu Hucheng's background online, and accidentally finds that Gu Hucheng and Xueya took a photo together. As the investigation deepens, Shen Xiulian finds out that Gu Hucheng's family once framed Xueya for stealing, and used the police to send Xueya back to China. Shen Xiulian went to the door to find Gu Hucheng to settle the account, and took a sharp weapon to hijack Gu Hucheng. Shen Xiulian accused Gu Hucheng's family of framing Xue Ya for stealing things back then. Gu Hucheng confessed that he only found out that Xue Ya was wronged after the fact. Now that Xue Ya has passed away, what he wants to do most is to find out the murderer.
Shen Xiulian stabbed Gu Hu in the chest with a sharp weapon, but Gu Hucheng was not angry, but proposed to join forces with Shen Xiulian, and the two of them tracked down the murderer together. Shen Xiulian is hostile to Gu Hucheng, and she declares that she will never join forces with Gu Hucheng.
Shen Xiulian walked out of the room and met Zhou Dantai and Wu Yunxi in the aisle. Zhou Dantai was taken aback and asked Shen Xiulian why she came out of Gu Hucheng's residence. Shen Xiulian stood on the spot, not knowing what to do. Gu Hucheng put on a coat and walked out the door, mentioning that someone had hung a banner to apologize for Xue Ya, and he originally wanted to cancel the cooperation with Zhou Dantai, but for Shen Xiulian's door-to-door plea, he decided to continue to cooperate with Zhou Dantai. Wu Yunxi hurried to help, praising Shen Xiulian as a virtuous internal helper.
Luna announces to Qian Ruizhen that she will drop out of school because she feels that she is not suitable to study at Qingya Art School. Qian Ruizhen could not get what she wanted, and pretended to remind Luna that she needed the consent of her guardian to drop out of school. Luna packed up her schoolbag and left the school without notifying her mother, Wu Yunxi. The classmates who bullied her were all smiles and wished her to leave school. Only Zhou Xiyun was so anxious that he followed behind for a while.
Zhou Dantai secretly instructed his subordinates to check the monitoring, and the subordinates found that Gu Hucheng appeared in the monitoring. After Zhou Dantai watched the surveillance, he remembered the scene when he pushed Xueya down the building with his own hands.
