Travel to Five Years Later with Her Boyfriend’s Older Brother

Ji Qingyu is a twenty-two-year-old web novelist and recent graduate who lands an internship at Yisheng Group. During her internship, she meets Feng Yu, the younger son of the company's chairman. Despite her initial reluctance due to her existing relationship with a senior colleague, Feng Yu pursues her persistently with grand romantic gestures. She eventually reciprocates his feelings, and they begin a sweet romance. Feng Yu proposes with a diamond ring and arranges for Ji Qingyu to meet his family. On the day of the meeting, a car accident causes Ji Qingyu to lose consciousness. When she wakes up, she finds herself on a private jet with Feng Chengze, Feng Yu's cold and stern older brother, who barely acknowledges her existence in her original timeline.

Assistant Zhang informs them that they are traveling to Jing City and that their daughter, Feng Jiayuan, is waiting at kindergarten. Ji Qingyu and Feng Chengze discover that they have traveled five years into the future. The phone Feng Chengze uses belongs to this future timeline, revealing that Ji Qingyu is now his wife and that they have a four-year-old daughter named Yuan Bao. The wallpaper and chat logs indicate a passionate and intimate marital relationship, which shocks Ji Qingyu, as she was engaged to his brother only hours ago. Feng Chengze, though initially disturbed by the prospect of being with his brother's former fiancée, accepts the reality to maintain stability for the family business and his public image.

The two agree to maintain the appearance of a happy marriage until they can find a way to return to their original timeline. Feng Chengze prioritizes his duties as the executive director of Yisheng Group, spending hours catching up on five years of missed business. Ji Qingyu explores their future life, discovering the luxurious lifestyle she has adopted, including expensive clothing, jewelry, and a close relationship with Assistant Zhang. She also listens to voice messages from her daughter, which helps her prepare for the upcoming meeting. Despite the strangeness of the situation, Ji Qingyu finds herself adapting to the role of a wealthy wife, though she remains anxious about meeting her daughter.

Upon arriving in Jing City, Feng Chengze and Ji Qingyu go to pick up Yuan Bao from kindergarten. The child is lively and affectionate, hugging both parents enthusiastically. Ji Qingyu struggles with the maternal instincts, feeling like an outsider, while Feng Chengze is awkward but gradually warms up to his daughter. They return to the Feng family mansion, where they are greeted by Feng Chengze's parents, Zheng Mingyue and Feng Jinglin. The home is filled with children's toys and decorations, a stark contrast to its usual solemn atmosphere. The grandparents dote on Yuan Bao, and the family dynamic appears harmonious, though underlying tensions regarding the relationship between the two brothers are hinted at.

During dinner, the family interacts warmly, but Ji Qingyu remains cautious, fearing she might slip up and reveal her true identity. She learns that Feng Yu is currently abroad and has not returned in several years, suggesting a significant rift between the brothers. Feng Chengze is concerned about his brother's well-being but maintains a composed exterior. As the evening progresses, Ji Qingyu and Feng Chengze navigate the complexities of their forced proximity. They share moments of awkwardness and unexpected intimacy, such as when Feng Chengze helps Ji Qingyu with her coffee preferences in front of Assistant Zhang. The story follows their attempts to balance their current lives with the uncertainty of their future, as they search for a way back while dealing with the emotional and social implications of their new identities.
