Cheng Yao, aspiring lawyer, secures a position at Junheng, a leading family law firm. Opting to live nearby, she faces an unexpected twist when her landlord double rents. Agreeing to share with another tenant at 80% of the rent, Cheng Yao is unaware that this seemingly harmless "housemate" is none other than Qian Heng, the boss at Junheng.

During Cheng Yao's first team meeting, she received a sharp reprimand from Qian Heng for her lack of proficiency in basic legal knowledge. It became evident that Qian Heng's harsh attitude was not just about pushing her out of the shared living space but also aiming to force her out of the law firm entirely. Unbeknownst to Cheng Yao, another partner at Junheng, Wu Jun, harbors a secret love for her sister, Cheng Xi, dating back to their student days. Wu Jun had covertly aided Cheng Yao in securing admission to Jun Heng, driven by his unrequited feelings for Cheng Xi, who had repeatedly rejected his attempts to bring her into the firm.

Late at night, Cheng Yao finds herself humming a song and cooking at her workstation. Consequently, Qian Heng ends up falling asleep on the office sofa. The next day, this unusual incident catches the attention of colleagues at the law firm. Despite its absurdity, Qian Heng has to face the reality that whenever Cheng Yao is around, he can easily doze off. Desiring a good night's sleep, he persuades Cheng Yao to consider a career switch and become his personal assistant. Unaware of his intentions, Cheng Yao finds Qian Heng's behavior odd but remains steadfast in her dream of becoming a lawyer.

Cheng Yao wakes up in a panic, but Qian Heng finds a pretext to have her move into the shared rental house. He uses a substantial compensation bill to coerce Cheng Yao into relocating and taking on the landlord's duties, including solving all of Qian Heng's life problems and preparing midnight snacks. Cheng Yao deeply regrets her intoxicated mistake but reluctantly agrees to Qian Heng's request, moving back to the shared rental house. Despite Qian Heng requesting Cheng Yao to prepare midnight snacks daily, he never actually consumes them, leaving Cheng Yao perplexed.

Cheng Yao doesn't take Qian Heng's words to heart and devotes herself to assisting Bai Xing Meng in finding evidence. However, Xu Jun had numerous companies, making the investigation challenging without complete information. Qian Heng, engrossed in the case all day, neglects to eat. He finally sleeps at midnight, only to be awakened by a stomachache. Reluctantly, he reheats the food in the refrigerator and consumes it. Surprisingly, a warmth spreads from his mouth to his stomach. Accustomed to high-end fast food, Qian Heng never anticipated that home-cooked dishes could be so delicious.

Upon learning about Cheng Yao and Cheng Xi's amusement park plans, Wu Jun reveals that the president of the Law Association instructs Qian Heng to accompany Cheng Yao to the event and emphasizes not to be absent for this year's Golden Scale Award. With excitement, Wu Jun heads to the amusement park, eagerly anticipating an "accidental encounter" with Cheng Xi. Meanwhile, Qian Heng takes Cheng Yao to the Law Association's activity, only to realize upon arrival that the so-called event is a law firm networking gathering. Left with no choice, they participate in the unexpected affair.

Bai Xing Meng privately approaches Cheng Yao, tearfully expressing concerns about being followed and threatened by Xu Jun. She pleads with Cheng Yao to reject Xu Jun on her behalf. Unable to ignore Bai Xing Meng's distress, Cheng Yao decides to support her and turn down Xu Jun's settlement request as per her plea. To their surprise, the next day brings news of Xu Jun's suicide by jumping off a building, accompanied by a suicide note. Xu Jun's tragic death becomes headline news. Bai Xing Meng, however, shifts all responsibility to Cheng Yao and engages Deng Ming's law firm instead. It is only then that Cheng Yao realizes Bai Xing Meng has taken advantage of her.

Concerned about the recent incident, Qian Heng keeps a close eye on Cheng Yao, fearing its impact on her. Sleep eludes him when he hears cries emanating from her room. Little did he know, Cheng Yao spends the night watching romantic movies in her room, and despite the tears, she emerges the next day brimming with energy. Taking inspiration from online suggestions, Qian Heng decides to implement some ideas from netizens to help Cheng Yao overcome her sadness.

Since her divorce, Cheng Xi has been actively involved in charitable work. However, Deng Ming has persistently bothered her. This time, he uses his sick mother's birthday as an excuse, hoping that Cheng Xi would visit her at the hospital. It is only during this visit that Cheng Xi discovers Deng Ming has not informed his mother about the divorce. Meanwhile, Wu Jun has been pursuing Cheng Xi closely. He expresses his interest in collaborating on public welfare initiatives at Junheng and invites Cheng Xi to join the efforts. Cheng Yao has reapplied to take on cases, and Qian Heng assigns her the divorce case involving the affluent Dong Shan.

Wu Jun, under the guise of being a public interest lawyer, requests to become Cheng Xi's assistant. Qian Heng states that there is no need to continue investigating Dong Shan's case, and Cheng Yao learns about Dong Shan's unexpected death in a car accident. The two attend Dong Shan's memorial service, where his wife, Jiang Wen Xiu, is overcome with grief. She earnestly asks Qian Heng and Cheng Yao to keep confidential the matter of Dong Shan's desire for a divorce before his death. Cheng Yao is moved by Jiang Wen Xiu's deep love for her deceased husband, but Qian Heng points out that Jiang Wen Xiu's haste to cremate Dong Shan is to prevent Chen Qing Mei from being able to verify her baby's DNA.

Cheng Yao shares his recent situation with her boss to Li Meng Ting. Li Meng Ting is sure that Qian Heng has feelings for Cheng Yao. To show her gratitude, she introduces the foot bath to Qian Heng. Qian Heng doesn't understand why Cheng Yao can always feel happy and excited about small things. She can feel happy about anything. They are moments that Qian Heng will not care about in his life. Qian Heng looks down on Cheng Yao's small-mindedness, but he is also being influenced by her attitude unknowingly.

Cheng Yao proposes to have a kinship test with Grandpa Dong and gains Qian Heng's approval. Cheng Yao convinces the traditional and male-preference-minded Grandpa Dong to undergo the kindship test but encounters difficulties and harsh words from the residents of the nursing home during the process. Deng Ming learns that Cheng Xi and Wu Jun have become close and visits Cheng Xi's residence to threaten her.

Cheng Yao and Qian Heng are both eager to thaw the strained relationship that resulted from the mistress incident. Qian Heng, under the pretext of flimsy excuses, attempts to spend the night at their shared unit. However, Cheng Yao, being oblivious, fails to discern his intentions. Seizing an opportunity, Qian Heng takes charge of a trust case involving the Tang Bing family from another city. He devises a plan to take Cheng Yao on a business trip, successfully convincing her to stay in the shared unit by emphasizing its proximity to the airport.

Tang Bing approaches Cheng Yao under the guise of an assistant, with the intention of engaging in sexual harassment. Remaining composed, Cheng Yao gathers evidence and cleverly uses it as leverage to escape the situation. Upon returning to her room, Cheng Yao is visibly shaken. Fortunately, Qian Heng arrives just in time and witnesses the incriminating video recorded by Cheng Yao. Without hesitation, Qian Heng confronts Tang Bing and adamantly refuses to work with him. While touched by Qian Heng's support, Cheng Yao can't shake off the concern that Qian Heng's actions may jeopardize his legal license.

Since Tang Bing's case is rejected, Qian Heng and Cheng Yao find themselves with a free day. To make it up to Cheng Yao, as promised, Qian Heng accompanies her to the amusement park. After a day filled with fun, the two return to the hotel feeling tired. As Qian Heng gazes at Cheng Yao's peaceful sleeping face, he drifts off to sleep himself, without any dreams, experiencing a restful night.

Upon returning to work the next day, Cheng Yao discovers that Qian Heng not only organizes a retreat but also secures a low-value case. To Cheng Yao's surprise, the opposing party's lawyer turns out to be Yao Feng, her ex-supervising lawyer who had previously bullied her. This realization moves Cheng Yao deeply and fuels a determination within her to work even harder and with more focus, as a way to express gratitude toward her boss for looking out for her.

Madam Qian questions Qian Heng and Cheng Yao about whether they are in a romantic relationship, but the two refuse to acknowledge it. Despite their denial, Madam Qian senses a subtle connection between them. She decides to play along and asks Cheng Yao for help in orchestrating a plan to trick Qian Heng into going on a blind date. Qian Heng eagerly agrees and goes to Cheng Yao's arranged meeting, only to discover that he has been deceived. As he is about to leave in frustration, he notices Cheng Yao's parents' presence. Instead of leaving quietly, he deliberately lets Cheng Yao's parents discover the situation, causing a scene. Despite Cheng Yao being scolded by her parents, she secretly rejoices that Qian Heng's attempt at a blind date has failed.

After leaving, Cheng Yao brings Li Meng Ting to the hotel to review the cause. Qian Heng waits for Cheng Yao at the car park. He follows her instructions and does a livestream while finishing the soup she prepared for him. People start to flood the livestream room. After helping Li Meng Ting to settle down, Cheng Yao realizes that Qian Heng didn't set a password for the livestream room. She rushes to the car park. She sees an exhausted Qian Heng sleeping in the car. Cheng Yao puts on a pair of earphones and watches the replay. She thinks that he's cute as she turns around to see him, getting slightly distracted.

Qian Heng, reluctant to move out and continuously postponing the packing process, finally reaches a point where he can't wait any longer. Angrily, he instructs Zhu to organize a seminar on "Maintaining Professional Boundaries at the Workplace." After moving back to the villa, Qian Heng finds it difficult to settle down and resorts to increasing his workload to distract himself. Cheng Yao, returning home from work, is met with disappointment as she faces the emptiness of the rented house. The following day, Qian Heng mistakenly believes that the lunchbox Cheng Yao brings is meant for him, only to realize he misunderstands her intention.

Qian Heng dreams that Cheng Yao wants to have a child with him. He goes to the office early as he cannot fall asleep after waking up from his dream. He realizes that the office is empty. After that, he realizes that everyone is attending the "No Relationship At Workplaces" seminar he arranged for. He begins to feel restless after Cheng Yao stops approaching him after confessing to him. He went online and searched for answers to why girls don't approach them after confessing to them to no avail. Qian Heng is perplexed.

Cheng Yao learns from Wu Jun that the gift might have been sent to the wrong person and so she suspects that she might have sent the wrong gift. Cheng Yao goes to Qian Heng's house, pondering where the gift might be placed. Surprisingly, upon entering the study, she finds her gift and card displayed prominently in the center of the room. Cheng Yao is thunderstruck as she reads the words on the card. At that moment, Qian Heng's parents appear, and Cheng Yao, holding the card, finds it difficult to explain herself. Qian Heng's mother expresses extreme surprise.
