“School Beauty CEO, We Agreed to Divorce—Don't Go Back on Your Word”

Shen Baizhou is a transmigrator who arrived in the parallel world of Blue Star with nothing but an 80,000 yuan debt and the memories of his previous life as an assistant director. After days of struggling to stabilize his situation, he is abruptly fired by his supervisor, Sheng Jiong, who plans to withhold his severance pay and bonus. Rather than complying, Shen Baizhou decides to delay his departure to secure one final day's wages. While leaving the company, he is intercepted by Su Hongdou, a stunningly beautiful woman driving a Porsche, who mistakenly believes he is her friend Xiao Shen. When the real Xiao Shen reveals the mix-up, Su Hongdou, desperate to avoid an arranged blind date, insists Shen Baizhou marry her instead. She offers him 35,000 yuan for a one-month fake marriage to fend off her family's pressure. Despite the absurdity, Shen Baizhou accepts the deal due to his dire financial situation.

After registering their marriage, Shen Baizhou returns to the office to confront Sheng Jiong. He publicly humiliates his supervisor by exposing his embezzlement of bonuses and his unethical reliance on a ghostwriter, known as the "No. 8 Black Stocking Technician," to complete scripts. Shen Baizhou threatens to release a recording of Sheng Jiong's threats unless he is compensated fairly. However, the company's director, Huang Liang, intervenes and reveals he knows Shen Baizhou's family address, threatening his aunt's safety to force him into silence. Huang Liang offers a seemingly impossible challenge: if Shen Baizhou can write a winning script for an upcoming microfilm competition overnight, he will be allowed to direct the film and keep his job; otherwise, he leaves with nothing.

Shen Baizhou accepts the challenge, relying on his knowledge of Earth's cinema to adapt the acclaimed short film "The Piano Tuner." Meanwhile, Su Hongdou discovers that her new husband works at her company, Jinxiu Media, where she is the reclusive CEO. She intervenes to protect him, but Huang Liang ensures Shen Baizhou has no access to company resources by locking him out of the office after hours. Homeless after being kicked out by his aunt, Shen Baizhou initially considers staying at the office but is forced out. He eventually returns to Su Hongdou's villa, where a series of comedic misunderstandings occur. Su Hongdou, raised with bodyguards and influenced by anime tropes, believes Shen Baizhou is a pervert and attempts to ambush him with martial arts. Instead, she accidentally attacks him while he is cooking, leading to a physical struggle that reveals her naivety and his unexpected combat skills.

That night, Shen Baizhou guards the villa against a suspected burglar, only to discover it is Su Hongdou sneaking downstairs for food. They bond over their shared love of anime and cooking, and Shen Baizhou helps her with her weight concerns using mathematics. The next day, Shen Baizhou races against time to finish his script. He manages to submit "The Piano Tuner" just before the deadline. The script's profound emotional impact and tight narrative stun the judges, who are accustomed to mediocre corporate productions. As the results are announced, Shen Baizhou faces the possibility of losing his career before it begins, while Su Hongdou watches from the sidelines, increasingly confused by her growing feelings for her fake husband. The story concludes with the anticipation of the competition results, setting the stage for Shen Baizhou's rise in the entertainment industry and the evolution of his relationship with Su Hongdou.
