This episode depicts the complete collapse of Su Yumian and Jiang Yihuai's six-year relationship. To give his new flame Shi Muxi "a title," Jiang Yihuai publicly betrays Su Yumian at a friend's party and breaks up with her on the spot. Su Yumian displays extraordinary composure and decisiveness, agreeing to the breakup immediately, sarcastically peeling and dividing an orange before walking away with a flourish. Jiang Yihuai and his friends arrogantly bet that Su Yumian will quickly come back, unaware that she has already packed her bags and taken the seventy million check Jiang Yihuai offered as "breakup money." Having seen through Jiang Yihuai's hypocrisy, Su Yumian decides to shed the burden of love, embrace freedom and wealth, and start a new life.

After a complete breakup with Jiang Yihuai, Su Yumian decisively cashed out a 70 million check and became a top VIP at the bank, showcasing her independence from the wealthy family. Faced with Jiang Yihuai's arrogant and dismissive "kept woman" label, Su Yumian resolutely chose to rebuild her life, planning to enroll in the graduate program of Professor Ouyang, a top scholar in the country. Following her friend's advice, Su Yumian learned about Shao Wenbai, a genius in the physics world and Professor Ouyang's favored student. Meanwhile, Shao Wenbai, who had just won an international award, hastily left the stage under everyone's gaze after mentioning "Su Yumian." It seems there's a hidden past between them, and the gears of fate begin to turn.

Su Yumian returns to campus elegantly dressed, stunning everyone. Her beauty even overshadows the current "campus belle," Shi Muxi. Envious, Shi Muxi confronts Su Yumian, using Jiang Yihuai as an excuse to verbally insult her, calling her an "old woman." Su Yumian calmly retorts, comparing Jiang Yihuai to "trash" she discarded, embarrassing Shi Muxi. Subsequently, campus heartthrob Professor Shao Wenbai appears. Ignoring Shi Muxi, he proactively invites Su Yumian to walk with him. Amidst the crowd's whispers, Shi Muxi is reduced to a mere accessory. In her resentment, she calls Jiang Yihuai, acting spoiled and demanding gifts, attempting to regain face by flaunting his attention.

Professor Ouyang Wenqiu, while hospitalized, reflects on his life and laments "three regrets": first, the vastness of scientific research and the brevity of life; second, having no children; and third, his beloved genius student Su Yumian abandoning her bright future for a man and disappearing for six years. Flashbacks reveal Su Yumian as the top science scorer in her year, solving a problem that had stumped everyone for eight years, astonishing the entire school. Just as Professor Ouyang is sighing with regret, his student Shao Wenbai enters with a mature-looking woman. Su Yumian, after six years, has finally returned to her teacher's side.

Su Yumian visits Professor Ouyang's home and finally earns her mentor's forgiveness through a sincere apology and her determination to retake the postgraduate entrance exam. Led by her senior classmate Shao Wenbai, Su Yumian heads to the laboratory. On the tree-lined campus path, she unexpectedly encounters her ex-boyfriend Jiang Yihuai and his new girlfriend Shi Muxi. Despite advice to avoid them, Su Yumian chooses to face them head-on, walking past Jiang Yihuai with a completely new demeanor. Jiang Yihuai is shocked by Su Yumian's transformation and even shows clear impatience with Shi Muxi, who is bothering him.

Jiang Yihuai intercepts Su Yumian in the park, mocking her for quickly finding a "campus nobody" (Shao Wenbai) as a replacement and humiliating them both with his possessive "territorial instinct." Su Yumian sharply retorts to Jiang Yihuai's rudeness, revealing that her years of "tolerance" were not forgiveness but a readiness to leave. Su Yumian decisively declares their relationship is "over," and leaves with Shao Wenbai. On their way out, Su Yumian apologizes to Shao Wenbai for her undignified behavior after the breakup. However, Shao Wenbai gently hints that this isn't their first meeting, leaving a mystery about their identities.

This episode intertwines memories and reality. In a flashback, Su Yumian faces collective ridicule from male students in the physics department due to her gender. She wagers her ability to solve a top-tier problem, forcing the boys who mocked her to crawl like dogs in public and win back her dignity. This experience also sparks her curiosity about the "prodigy senior" Shao Wenbai, who posed the challenge. In the present, the now-estranged Su Yumian is searching for housing. Shao Wenbai, under the guise of "a friend's urgent rental," offers her a luxurious mansion worth fifty thousand yuan for a mere five hundred yuan. He even deliberately conceals his identity to avoid hurting her pride, and they become next-door neighbors. Meanwhile, her ex-boyfriend Jiang Yihuai, suffering from stomach pain with no one to care for him, begins to miss Su Yumian's presence and unexpectedly discovers her old phone.
