Episode 12 recap: Xiao Lan asked Ma La Song to arrange a meeting with Liu Yueyang.

On the way back, Ma La Song told Qi Heng that they had actually met Qi Heng ten years ago. Qi Heng had come to their school to give a speech. However, on the way, their car encountered a problem, and they found out that the person who helped them fix the car was actually the delivery guy. He expressed gratitude to Ma La Song for the verdict in his case, as it allowed him to continue his business without the burden of a conviction.

Ma La Song was also happy to see that the person had found their own value again. As soon as Qi Heng returned to the office, Niu Geng was already waiting there. Niu Geng asked Qi Heng to return Ma La Song and Liu Yueyang to him, as there were still many things to be done in Criminal Division One.

Niu Geng earnestly pleaded with Qi Heng, and Qi Heng reluctantly agreed. Soon, Ma La Song and Liu Yueyang returned, and Niu Geng was very happy. He even said that he would entrust them with anything they needed in the future. Wang Mo was also delighted to have both good colleagues back, and Niu Geng said he would pass on all his lifelong knowledge and skills to them.

At this time, a man named Luo Di was preparing to jump off a building. The police were trying to persuade him, but his wife was completely indifferent. Luo Di was pleading with his wife not to divorce him, but she paid no attention. Accidentally, he fell and stabbed a man who was holding a knife below him, killing him.

Luo Di himself was not seriously injured, just a bit dizzy. The court quickly tried this case, and Luo Di and the owner of the kitchen knife, Xue Qin, were brought to trial. The prosecutor charged Xue Qin and Luo Di. Xue Qin was taken away first, and then they began questioning Luo Di. However, Luo Di denied that he intended to commit suicide. He claimed that he was only drinking on the rooftop, and it was a misunderstanding that he was thought to be jumping off. He decided to play along because his wife wanted a divorce, and he wanted to scare her a little, but he never expected to fall.

He never actually intended to die. Luo Di also mentioned that he had acrophobia, so he would never consider jumping off a building.

Luo Di just suddenly stood up and saw someone below, which startled him and caused him to accidentally fall. Next, the defendant Xue Qin was summoned. Xue Qin is the victim's younger sister, and she was also very emotionally agitated. Initially, Xue Qin was cooking at home, but because she sold the house to Luo Di's wife, she had nowhere to live and was stubbornly staying at home. The court came for mediation, and Xue Qin's emotions were highly charged. Xue Qin even tried to act difficult.

Later, Xue Qin mentioned that Luo Di's wife, Wang Bi Yao, was a fraud. About six months ago, Xue Qin had invested in some financial products and needed two million yuan. Xue Qin thought of entrusting the house to the real estate agent, Wang Bi Yao, who happened to be looking to buy a house and purchased the property in full. Later, Xue Qin realized that she had been deceived.

When the court ordered her to move out, Xue Qin became extremely emotional. Qi Heng asked everyone to adjourn temporarily and continue the trial in the afternoon. After returning, they discussed the matter together, and everyone felt that the case was very bizarre, so they needed to pay attention to the emotional state of the defendant in the afternoon. Xiao Lan found Ma La Song and presented two movie tickets, hoping that Ma La Song could help them arrange a date with their crush, Liu Yueyang. However, Ma La Song wanted to refuse, while Xiao Lan kept pleading.

In the afternoon, the trial continued, and Wang Bi Yao was called as a witness to present evidence. Wang Bi Yao also expressed her contempt for Luo Di, saying that she wanted to divorce him. Luo Di, on the other hand, kept crying and refused to sign the divorce papers. He cried and threatened Wang Bi Yao with suicide, but she didn't care at all.

Luo Di never actually intended to commit suicide, and as for jumping off the rooftop, Wang Bi Yao didn't see it clearly. When it was Xue Qin's turn, the judge from the court appeared as a witness. The judge stated that Xue Qin intentionally threw the kitchen knife, but did not expect it to land on her brother's body.
