Three years after their painful separation, Sang Wuyan and Su Nianqin are still struggling with their unresolved feelings. Wuyan returns to her part-time job at the local radio station and is surprised to see Nie Xi there. Nie Xi apologises for the way she treated Wuyan in the past, admitting that she once had feelings for Nianqin and behaved out of jealousy. She eventually realised that Nianqin's heart belonged to Wuyan, and she has now accepted that their relationship was never going to be hers. Nianqin is determined to reconcile with Wuyan. He arranges to pick her up after work and plans to take her to dinner, hoping to spend time with her and repair their relationship. However, he sees her getting into Wu Yu's car before he can approach her. Jealous and upset, he follows them to a restaurant. Wu Yu has invited Wuyan to dinner to give her children's picture books brought back from Japan by a friend, believing they will be useful for Xiaojie, the autistic child she works with. Wuyan accepts the invitation because the books may help Xiaojie, but Nianqin interprets their meeting as a sign that another man may be becoming important in her life. Unable to hide his jealousy, Nianqin calls Wuyan outside. He pulls her aside and confronts her about spending time with Wu Yu. His words become increasingly possessive, and he declares that unless he dies, she cannot expect to be with another man. When he notices that she has been drinking, his jealousy intensifies. In the heat of the confrontation, he kisses her forcefully, then admits how deeply he has suffered during their years apart. He confesses that once he falls in love, he finds it almost impossible to let go, and he is terrified that Wuyan may have fallen for someone else. Wuyan is shaken by Nianqin's outburst. After returning home, she receives a call from Wu Yu, who checks that she is all right after being left at the restaurant. Wuyan apologises for the awkward situation and clearly tells him that they are not suited to a romantic relationship. Wu Yu accepts her decision and says they can remain friends, leaving the future of their relationship open without pressuring her. At the research centre, Xiaojie becomes agitated and difficult to calm. Nianqin arrives looking for Wuyan and encounters the child. Rather than forcing Xiaojie to respond, he sits at the piano in the classroom and begins to play. The music gradually draws Xiaojie's attention, and the boy settles down beside him to listen. Wuyan witnesses the scene and is touched by Nianqin's patience and the natural connection he forms with Xiaojie. Seeing him interact gently with the child reminds her of the kindness and understanding she once loved in him. Nianqin also returns the watch that had become caught up in their misunderstanding. He tells Wuyan that a gift, once given, should not be taken back. His words suggest that he does not want her to erase the emotional connection between them, even if she is still unwilling to resume their relationship. He then uses the excuse of not having a dance partner to persuade her to accompany him to a business banquet. At the banquet, Wuyan feels out of place among the wealthy guests and spends much of her time sampling the food. A young man named Peng Ruixing approaches her and asks how someone dressed so casually has entered such an exclusive event. Wuyan jokingly claims that she is there to test whether the food has been poisoned. Her humorous response amuses Peng Ruixing, who finds her intriguing, but Wuyan has little interest in chatting with someone she assumes is a spoiled rich playboy. As she turns to leave, she accidentally pulls the tablecloth and causes a small commotion. The incident draws attention to Wuyan, and the guests begin questioning who she is. It is then revealed that Peng Ruixing is the young heir of the Tuoluo Company and the younger brother of Peng, a woman who has feelings for Nianqin. Before the situation can become more uncomfortable, Nianqin steps forward and introduces Wuyan as his fiancée. The announcement shocks the guests, especially Peng, who had hoped to get closer to him. Wuyan is equally surprised that Nianqin has publicly declared a relationship she has not agreed to resume. After the banquet, Nianqin explains his reasoning. He recalls that during their argument three years earlier, Wuyan said that if he was willing, they could register their marriage after she returned from visiting her father. He treats those words as a promise and argues that they should now get married. Wuyan rejects the idea, explaining that he cannot decide their future on the basis of something said during an emotional moment. She feels overwhelmed by his forceful approach and tells him that his insistence is making it difficult for her to breathe emotionally. The next day, Nianqin summons Wei Hao to the company. Using his position as Wei Hao's boss, he presses him for advice about how he and Xu Qian managed to overcome their relationship problems and eventually marry. Wei Hao initially resists discussing his private life, but soon understands that Nianqin genuinely wants to win Wuyan back. He tells Nianqin that he must decide whether Wuyan matters more to him than his pride. If he truly wants her, he must stop trying to control every situation and learn to lower his guard, listen to her, and make an honest effort to earn her trust. Nianqin begins trying to follow this advice. He looks for ways to show Wuyan his feelings through small gestures, including writing messages for her with leaves and going out of his way to help her when it rains. Although his actions reveal how much he still cares, his possessiveness and insistence on marriage continue to frustrate Wuyan. She wants him to understand that reconciliation must be a mutual decision rather than something he can force. Episode 19 ends with Nianqin determined to pursue Wuyan again, while Wuyan remains caught between her lingering love and her fear of repeating the painful mistakes of their past. His public declaration that she is his fiancée makes their unresolved relationship impossible to ignore, setting up further emotional confrontations as he tries to prove that he has changed.
