Episode 16 recap: Duan Jia Xu has repeatedly broken his promises.

Sang Zhi opened the gift that Duan Jia Xu sent, and it was a camera with a selfie photo of Duan Jia Xu's collarbone inside. Sang Zhi felt Duan Jia Xu was shameless, and he even messaged her asking if she liked the photo. Sang Zhi said the photo was not clear, and Duan Jia Xu said he would immediately send her a high-definition version if she agreed. Sang Zhi defined this as the tricks of a scheming old man.

After saying goodnight, Sang Zhi changed Duan Jia Xu's contact name from "Brother No. 2" to "Suitor". Sang Yan sent her a red envelope and Sang Zhi told him she might start dating someone, and that the person was a bit older. Sang Yan immediately became flustered and called to warn her not to date and to focus on her studies.

Ning Wei said Sang Zhi should think carefully about when to agree to Duan Jia Xu, and also protect herself. Sang Zhi was still a bit worried, afraid Duan Jia Xu was just acting on a whim. However, her roommate reminded her that if she was really worried, she could test him.

Sang Zhi put on the bracelet Duan Jia Xu sent in three minutes, and then he immediately messaged to ask if she was free tomorrow. As Sang Zhi was about to reply, Ning Wei snatched the phone and said no. Duan Jia Xu, puzzled by the message, then asked about the day after. Sang Zhi again said she might not be free, and Duan Jia Xu immediately sought help from his colleague, realizing Sang Zhi was testing his sincerity.

Duan Jia Xu then asked about Thursday evening, and Sang Zhi agreed after looking at Ning Wei. On Thursday, Sang Zhi dressed up nicely, but Duan Jia Xu called to say he couldn't join her for dinner due to various issues. Then the second time, Duan Jia Xu again broke the date due to work problems. After these repeated instances, Sang Zhi became a bit depressed, wondering if Duan Jia Xu was really putting in the effort to pursue her.

Until the nth time, even Sang Zhi's roommates were indignant on her behalf.

After being stood up again, Sang Zhi returned to the dorm with an indifferent look on her face. This time it wasn't due to work, but she didn't bother asking about it either. Duan Jia Xu had gone to a nursing home, as his father had become a vegetable after a car accident a few years ago, and his recent condition was not good.

That night, Duan Jia Xu's father came home and fearfully told Duan Jia Xu and his mother that he had hit someone. His mother and Duan Jia Xu both urged him to turn himself in, but to their shock, he jumped off the building downstairs. From then on, Duan Jia Xu had been living a life of working to earn money. He originally didn't plan to go to Nanwu University, but it was his mother's insistence that made him complete his studies.

Later, Duan Jia Xu's mother also fell ill, and Duan Jia Xu and Sang Yan's family borrowed 30,000 yuan to help her get better treatment. However, his mother didn't want them to incur more debt for her sake, adding to the pressure she was already under. Duan Jia Xu returned home exhausted, and although Sang Zhi messaged him without much enthusiasm, she still decided to give him a call and say she wanted to see him.

Without hesitation, Sang Zhi's roommate put a bag on her back and went out with her. Duan Jia Xu often broke his promises, and Sang Zhi was indeed not very happy about it, but she understood it was because of his work and wasn't angry. Sang Zhi went to a nearby stall and bought Duan Jia Xu some cotton candy, saying that eating sweets could make him feel better when he was unhappy. This was the first time Duan Jia Xu had been comforted in this way, and it lifted his mood.

Afterwards, Duan Jia Xu concluded that Sang Zhi had already agreed to be with him, after all, who would make cotton candy for just an ordinary friend? Sang Zhi was quite speechless, and could only advise him to look up online how to properly pursue a woman. Duan Jia Xu quickly acknowledged his mistake and promised to seriously and diligently pursue her from that day on.

Sang Zhi had a sharing event to attend on the weekend, and Duan Jia Xu also came to participate.
