Episode 21 recap: Cheng Bing and Wang Miao Miao had a heart-to-heart talk.

Liu Zi called Xiao Xu over and said that he had thought about it all night and still felt something was wrong. The person at that time really wanted to kill him, and if someone hadn't come over, he would have definitely been dead by now. Liu Zi felt that he couldn't possibly have such a big grudge with anyone to want to kill him like that, there was only one person who would do something like that, and that person was Wang Da Yong.

Lin Ying and the others went to the nursing home and asked Wang Da Yong's mother's roommate. The roommate said that she was startled when she saw someone by the bedside and called out, and that person ran away. She wanted to turn on the lights but found out there was no electricity. She heard Wang Da Yong's mother calling for someone named Da Yong.

Liu Zi and the others also told Pan Da Hai about this incident and believed that it must be Wang Da Yong. Lao Ma and the others discussed it and felt that they didn't have the authority to investigate, so they had to call Lin Ying. The others also felt that they all had families now and couldn't act like they used to.

Wang Miao Miao had a stomachache and went to the restroom, and at that moment, her phone rang. She asked Cheng Bing to answer it. Cheng Bing picked up the call, but there was no response on the other end. Cai Bin and Xiao Xu had been following Liu Wen Fang and Tong Tong, thinking that their lives were too regular, and Wang Da Yong wasn't stupid, he would definitely figure it out.

Cai Bin and Xiao Xu noticed someone following them and subdued the person, only to find out that it was someone Pan Da Hai sent to protect them. Pan Da Hai came to find them and asked who told them to keep an eye on Liu Wen Fang. Xiao Xu and the others said it was for protection.

Pan Da Hai said they were alerting the enemy, as he had already sent Lin Ying over. Pan Da Hai told them not to interfere in this matter anymore, but Xiao Xu and the others disagreed. They believed that the Three Big Teams had become like this because of Wang Da Yong, and now they definitely had to catch Wang Da Yong.

Shi Tou also returned and said he heard that Wang Da Yong had come back to Ningzhou, so he came to catch him. Pan Da Hai was also frustrated and told them to just do as they wished.

Cheng Bing knew that Wang Miao Miao had a stomachache from eating the company's food, so he cooked a meal for her. Wang Miao Miao talked to him about past events, and Cheng Bing mentioned that he used to be busy with work and didn't have the opportunity to cook.

Everyone had been keeping watch here for several days, but there was no sign of any activity, so they didn't think it was a big deal. Lao Ma actually agreed with Pan Da Hai's statement. Liu Zi suggested that he should go and lure Wang Da Yong out himself, but Lao Ma advised Liu Zi to think it through, as Wang Da Yong was a desperate character.

Liu Zi believed that it would be better for himself to be targeted rather than Tong Tong. Liu Zi came out to lure Wang Da Yong out, with Lao Ma and the others following behind. Someone on a motorcycle rushed towards Liu Zi, but luckily Liu Zi managed to dodge. There were actually police officers watching the scene as well, and they all apprehended the person, but it turned out not to be Wang Da Yong, which greatly disappointed Lao Ma and the others.

Soon it was Mid-Autumn Festival, and Cheng Bing and Wang Miao Miao bought gifts for each other, making them both very happy. Wang Miao Miao mentioned her own situation, saying that no one had ever been as kind to her as Cheng Bing. Cheng Bing felt that Wang Miao Miao had also made him experience what it felt like to have a daughter.

The next day, Wang Miao Miao discovered that Cheng Bing had a fever and hurriedly took him to the hospital. Wang Miao Miao went back to pack her things and accidentally found the handmade bracelet she had made as a child in Cheng Bing's bag. That's when she realized that Cheng Bing was the police officer from back then, and she was extremely shocked.

Cheng Bing, seeing that Wang Miao Miao hadn't gone to the hospital, felt worried and returned first. Wang Miao Miao didn't say anything, but in the evening, she took a knife and approached Cheng Bing's bed, hesitated for a moment, and then stabbed it down.
