In the 13th episode of "I May Love You," Tang Yu attends Tang Xin's birthday party in a grand manner. Tang Yu finds various excuses to spend more time at Tang Xin's place and even shows affection towards a stray cat, despite his lack of interest in it. Tang Xin sees through Tang Yu's intentions but chooses not to confront him, allowing him to continue his actions.

Tang Yu expresses his desire to read Tang Xin's script, but Tang Xin stops him, stating that it's not good enough yet. Tang Yu argues that each work is like a child to the author and must have confidence. He believes that Tang Xin can do better because this work is not only Tang Xin's child but also his own. Tang Xin senses something amiss and accuses Tang Yu of taking advantage of her.

Meanwhile, Tang Ding Ding worries about her acting skills and seeks Huo Chen Dong's help to find a teacher for herself. However, Huo Chen Dong doesn't have much faith in Tang Ding Ding and suggests that she leaves the entertainment industry, which earns him a disdainful look from Tang Ding Ding.

The Tang family is against Tang Ding Ding pursuing an acting career, and they take turns trying to persuade her. But Tang Ding Ding remains determined to become an actress, even if it means enduring hardships. Despite her busy schedule, Tang Ding Ding doesn't forget to support her brother. She informs Tang Yu that their sister group's dress code for the upcoming birthday party is princess style. Tang Yu tries various means to gather information and finally sees the dress style she wants to wear at Tang Xin's house. Back home, Tang Yu puts on a personal fashion show and selects a dress that complements Tang Xin's outfit. However, to his surprise, Tang Xin is not wearing the dress he chose. It turns out that the dress was given to Tang Xin by You Huan. Fortunately, Tang Yu's dress still goes well with Tang Xin's attire.

Dressed up, Tang Yu accompanies Tang Xin to Diandian's birthday banquet, attracting the attention of everyone present. Diandian didn't expect them to be so high-profile and speculates that they are obsessed with playing the role of the Smith couple. Tang Mom also brings the blind date she arranged for her son to the party. Tang Yu openly declares that he has feelings for someone and points Tang Xin out to her. Tang Mom tries to approach Tang Xin but is stopped by Tang Yu. She can only observe Tang Xin from a distance along with Tang Dad, and both seem satisfied with her appearance.

Diandian reminds Tang Xin that the girl their mom introduced to their brother is also present. Tang Xin pretends to be indifferent, but she is actually conflicted. Tang Yu takes the initiative to help Tang Xin get some food and prevents her from drinking more. Diandian teases them, but Tang Mom immediately pulls her away.

After returning home, Tang Yu continues to enjoy the brief and cozy moments at Tang Xin's place, which only last for thirty minutes. They engage in casual conversation, and Tang Xin asks Tang Yu to help her write a script since he seems idle. Tang Yu informs Tang Xin that he has an important business trip the next day, so he wanted to spend more time with her today. Tang Xin is deeply touched by his tenderness.

The next day, Tang Xin's parents make a video call and inform her that Aunt Lin's son's company has relocated to Nangang. They intend to bring the two of them together. Tang Xin tries to make excuses, but her parents have already booked their tickets and insist on coming to make the arrangement. Reluctantly, Tang Xin welcomes her parents, but she feels hesitant because they have come with a specific purpose. Tang Dad is confident and determined to train his daughter to become a love expert. Tang Xin had previously shared her heartbreak with her parents, which has left a negative impression of Tang Yu on them. Worried that Tang Yu's meeting with her parents might cause unnecessary trouble, Tang Xin sends him a message asking him not to stay in the neighboring room for the time being. However, Tang Yu insists on visiting her on his own.

The TV media is playing rumors about Tang Yu and Lu Chu Ning. Tang Xin's parents see it and develop even stronger hatred towards Tang Yu. When Tang Yu returns from his business trip and is about to leave, he sees Tang Xin's parents coming back from grocery shopping. He intends to greet them, but then he sees Tang Xin coming out. Tang Xin is afraid that her parents will interrogate Tang Yu about her past heartbreak, so she quickly pulls them inside the house, not even giving them a chance to speak.

Gao Heng comes to find Tang Yu and sees Tang Xin in the elevator. He learns that she is going to meet a blind date, and he hurriedly reports this news to Tang Yu.
