One impulsive night changes everything. She thinks she betrayed her boyfriend—until she finds out he did it first. So she walks away… and marries the man she barely knows. Only problem? He’s far more connected to her past than she realizes.

This episode revolves around "suspicion" and "counterattack." Rong Che encounters his adoptive father, Rong Junheng, rushing out of a hotel and keenly notices a hickey on his neck, sparking a flood of doubts. Meanwhile, the Ruan mother and daughter (Lin Qinglan and Ruan Jiajia) viciously curse Ruan Zhi inside the villa, believing their scheme has succeeded and discussing how to seize the family fortune using the scandal. Ruan Zhi suddenly appears, launching a powerful counterattack and slapping Ruan Jiajia, igniting a chaotic brawl within the family. At a crucial moment, Ruan Zhi's uncle (Ruan Jiajia's father) appears and intervenes. Through Rong Che's suspicions and the fierce conflict within the Ruan family, this episode foreshadows the eruption of multiple conflicts.

Ruan Zhi confronts Ruan Jiajia and her mother in the Ruan family home, exposing Ruan Jiajia's plot to drug her the previous night to seize her inheritance, and presents a recording as evidence. However, while Ruan Zhi's uncle punishes Ruan Jiajia, he demands Ruan Zhi conceal the truth for the sake of the family's reputation. Seeing through her uncle's favoritism towards his own daughter, Ruan Zhi resolutely decides to move out of the Ruan family home and live independently. On a rainy night as she leaves, Ruan Zhi collapses on a roadside bench from exhaustion and is coincidentally rescued by Rong Junheng, the president of Rong Group, who is searching for "the girl from last night."

Ruan Zhi is drugged and framed by her cousin Ruan Jiajia and her mother, leading to an unexpected one-night stand with the wealthy and powerful Rong Junheng. The next morning, Ruan Zhi wakes up at the Rong residence and faces the stranger who saved her and took her virginity. She insists on keeping their encounter an accident and moving on separately. Rong Junheng is surprised by their 16-year age gap and the fact that Ruan Zhi is a virgin. Ruan Zhi mentions her boyfriend Rong Che (A Che) and her loyalty to him, unaware that her boyfriend is Rong Junheng's adopted son. Rong Junheng respects Ruan Zhi's decision, promising she can find him anytime if she changes her mind, and has her escorted away.

This episode unveils intricate character relationships. Rong Che senses a woman (Ruan Zhi) in his adoptive father Rong Junheng's life and attempts to intern at the company early, only to be rejected a second time by Rong Junheng under the guise of an assessment. Rong Che confesses he has a serious girlfriend named "Ruan Ruan" (Ruan Zhi) and plans to marry after graduation. Meanwhile, Rong Junheng, learning that Ruan Zhi not only rejected his farewell but also discarded his business card and ointment, becomes curious and tasks A Xing with investigating the background of Rong Che's girlfriend. Concurrently, Ruan Zhi, framed by her cousin Ruan Jiajia and aunt Lin Qinglan with drugs, loses her innocence and suffers facial injuries. After crying to her senior classmate, she decides to leave the Ruan family, only to unexpectedly discover that her friend Xia Shan has secretly started dating and moved out of the dormitory without her knowledge.

Ruan Zhi faces a housing crisis after her roommate Xia Shan hides her relationship and moves out. Her senior offers a helping hand by inviting Ruan Zhi to live with her. Meanwhile, her boyfriend Rong Che calls, wanting to introduce Ruan Zhi to his parents just before their one-year anniversary. Ruan Zhi is deeply unsettled, as she has a past experience of being a "victim" that she hasn't confessed. Her senior advises her to keep it a secret to avoid further harm, but after much deliberation, Ruan Zhi decides to be honest with Rong Che for the sake of their serious relationship.

This episode reveals Rong Che's extremely hypocritical and chaotic private life: while preparing to introduce his official girlfriend Ruan Zhi to his parents, he is secretly involved with Ruan Zhi's best friend, Xia Shan. Xia Shan provokes Rong Che in a hotel room, only to be coldly warned by him. Ruan Zhi, dressed elegantly for their meeting, is inwardly wavering and planning to confront Rong Che. Meanwhile, Rong Junheng observes from his car and, through his assistant A Xing's investigation report, exposes the scummy behavior of his adopted son, Rong Che, who is keeping a mistress and squandering money. To Rong Junheng's greatest shock, the "girlfriend" Rong Che refers to is actually Ruan Zhi, the very person he has been searching for or keeping an eye on.

In this episode, Rong Che deeply pledges his future to Ruan Zhi and proposes, hoping they can marry after her graduation. Ruan Zhi struggles internally, trying to confess the truth about what happened to her that night at the hotel. Just as Ruan Zhi gathers the courage to speak, Rong Che's adoptive father, Rong Junheng, arrives at the restaurant. Ruan Zhi is terrified to discover that the man who changed her destiny and entangled her in a one-night affair is none other than Rong Che's father. This overlapping identity plunges Ruan Zhi into extreme shock and awkwardness.

Ruan Zhi visits her boyfriend Rong Che's parents, only to be shocked to discover that Rong Che's adoptive father, Rong Junheng, is the mysterious man she had a one-night stand with not long ago. Under Rong Junheng's oppressive gaze and suggestive words, Ruan Zhi is restless and tries desperately to escape, even faking a headache to leave. However, Rong Junheng presses closer, taunting her for being "quite bold." Ruan Zhi finally breaks down and hides in the bathroom, consumed by extreme panic over her misplaced identity and ethical dilemma.

Ruan Zhi is cornered by Rong Junheng in the restroom, who forces her to break up with his son, Rong Che. Ruan Zhi is in extreme pain and struggles, revealing that she and Rong Che once had a one-night stand and questioning why Rong Junheng didn't push her away at the time. Despite his overbearing words, Rong Junheng shows a hint of guilt under Ruan Zhi's questioning. At this moment, Rong Che, who has been searching for Ruan Zhi everywhere, follows her phone's ringing sound into the men's restroom and stumbles upon their tense and ambiguous confrontation.

One impulsive night changes everything. She thinks she betrayed her boyfriend—until she finds out he did it first. So she walks away… and marries the man she barely knows. Only problem? He’s far more connected to her past than she realizes.
