Episode 24 recap: Xu Mai jumped off the building and died.

Lu Gaoyuan went to the hospital to see Pan Yueyang. He felt that Pan Yueyang had resentment towards him. This time he didn't bring anything except his ears, prepared to let Pan Yueyang scold him to vent his frustrations and hopefully get better. Pan Yueyang honestly said that he didn't hold such a big grudge against Lu Gaoyuan. However, it was not as simple as having a grudge against Gong Qi, who refused to meet them twice. There were pieces of evidence collected by Lu Shan in the drawer. Pan Yueyang asked Lu Gaoyuan to take them out and look at them. Lu Gaoyuan looked at the identical eyes of Gong Qi and compared them to Gong Qi's experiences over the years, but still couldn't understand.

Pan Yueyang knew about Lu Gaoyuan and Gong Qi's past. When he learned that Lu Shan had a massive gastric bleeding, he encountered Gong Qi in the corridor. He regretted believing in Lu Gaoyuan and Gong Qi before and was happy to see them continue their relationship after being widowed. Now it seems that Lu Gaoyuan and Gong Qi were the ones who killed his own sister.

Xu Jiayin took Lu Jiang to Xu Mai's residence to investigate. Just as she was about to sit down, Lu Jiang reminded her not to touch anything and to try to preserve it as it was. Lu Shan carefully observed the current state of the room and noticed a lighter corner exposed under the table. As he picked it up, he asked Xu Jiayin if Xu Mai smoked. Xu Jiayin said that Xu Mai didn't smoke originally, but recently she saw him using something similar to an electronic cigarette. Xu Jiayin couldn't provide a detailed description as she couldn't remember clearly.

Just as Lu Jiang put the lighter into an evidence bag, Wei Hong Jun called, asking him to quickly gather at Jiangshankou. Xiao Zhi had sent a message suspecting that the Falcon was on the move again. Wei Hong Jun and Lu Jiang rushed over.

Lu Jiang and Wei Hong Jun arrived at the abandoned steel factory and learned that the cars left at the scene were all stolen vehicles with drugs found inside. There was a lighter identical to Xu Mai's among them. Lu Jiang looked around and found Xu Mai's motorcycle there, which was also stolen and had fake license plates. He didn't believe Xu Mai would be foolish enough to be involved in this.

At that moment, Lu Qi sent a message saying that Xu Mai had turned on his phone but quickly turned it off. Xu Mai's location was traced to Xinxing Building. Xu Jiayin immediately called Lu Jiang and informed him that Xu Mai had just messaged her, asking her to take care of Yan Qingqing, and then the phone turned off again.

Lu Jiang realized that Xu Mai was in danger and urgently asked Xu Jiayin to rush to Xinxing Building while he and Wei Hong Jun headed there as well. Xu Mai stood on the rooftop, looking at the bustling city lights, and had another hallucination. He saw Su Pan inviting him to live together and couldn't help but walk towards Su Pan.

When Xu Jiayin arrived, Xu Mai was already standing on the edge of the rooftop. She shouted desperately, asking Xu Mai not to jump. However, Xu Mai, yearning for a happy life with Su Pan, without hesitation, jumped and died on the spot.

Xu Jiayin witnessed this scene with her own eyes and fainted directly. Xu Keji learned about the news and rushed to the police station, where he saw Xu Mai's words of blame directed towards him, causing him immense regret and shedding tears of sorrow.

From Xu Mai leaving home to his drug-induced suicide, everyone found it difficult to understand. The police suspected that Xu Mai might have been protecting Xu Keji, or that drugs had caused hallucinations leading to his jumping off the building. Lu Jiang felt that Xu Keji was not the type of person to push Xu Mai forward to take the blame. After seeing Xu Keji's heartbreaking state, he became even more certain of his judgment.

When Xu Jiayin was studying abroad, she longed for the warmth of home. After completing her graduate studies, she returned to China, but home was no longer the same as she remembered. The people in her family had changed significantly. Xu Jia Yin had no understanding of Xu Mai's circle of friends, but she was certain that Xu Mai started using drugs after Yan Qingqing was admitted to the sanatorium.

Xu Jiayin went home to visit Xu Keji and was shocked to learn that Xu Mai had been using drugs. Xu Keji deeply regretted not keeping a closer eye on Xu Mai and blamed himself for leading him down a path of no return. Overwhelmed by remorse, Xu Keji knelt down and burst into tears, while Xu Jiayin tried to console him while shedding tears herself. The father and daughter were filled with immense sadness.

Jia Lin, who was outside the door, had a slight change in expression upon hearing Xu Keji and Xu Jiayin crying. Lu Jiang went to deliver breakfast to Xu Jiayin and, seeing her exhausted appearance, knew that she hadn't slept all night. He advised her to take care of herself and promised to keep in touch. He assured her that he would notify her as soon as there were any developments in Xu Mai's case.

Xu Jiayin retrieved the items related to Su Pan that Xu Mai had cherished for a long time. She expressed gratitude to Su Pan for allowing Xu Mai to experience love and entrusted Lu Jiang to deliver the box of items to Su Pan. Lu Jiang asked Lu Gaoyuan for help in analyzing the drug samples and learned that Xu Mai had been using a new type of drug. This drug had a small dosage, caused quick and long-lasting hallucinations, and raised suspicions about its source.
