According to my knowledge of online novels, there are currently no novels where the female protagonist swapped her heart for the male protagonist's first love girlfriend. This kind of plot was more common and could be called " betrayal "," deception ", and other negative plots. If you want to write a similar story, I suggest rethinking the plot to make it more reasonable and attractive.
I recommend I Am Zeng Xiaoxian to you. The plot of this novel is very similar to the information you provided. The male protagonist was also a radio host. His first love had gone missing, and his girlfriend was going to marry him. As for the female lead, she was a fan of the male lead and had been paying attention to him silently. When the male protagonist encountered difficulties, he was able to tide over the difficulties with the help of the female protagonist. This story also had many celebrities in the entertainment industry appearing, which was very satisfying. I hope you like this fairy's recommendation. Muah ~π
For this plot to appear in a novel or movie, you can refer to the following answer: The female lead was framed by the second female lead. When the male lead and the second female lead got married, the female lead jumped off a cliff. The female lead lost her memory and changed her surname to Nangong. The second female lead was an athlete. The female lead first wore a mask and danced amazingly in the first chapter. This plot could be used to draw out the protagonist of the story and show her background and experiences. After losing her memory after jumping off a cliff, the female protagonist might need time to adapt to her new life and join a new team or organization. In this new environment, she might meet other characters and show off her different skills and talents. The female protagonist changed her surname to Nangong Nuer because her father or family had a background or influence in a certain place. This might lead to some complicated relationships and character relationships to lay the foundation for the development of the story. The main character's stunning dance in the first chapter with a mask may have been to attract the reader's attention and provide a striking start to the story. This performance could showcase the skills and charm of the female protagonist, and it could also attract the interest of readers, making them want to know more about her story and background.
The title of this novel might be " The Prince's Princess " or " The Prince's Princess of Time Travel ". These names all contained the plot where the female lead was a princess and the male lead was a prince. On their wedding night, the male lead gave the female lead's first night to his friend.
πThe novel I recommend to you is "The Beauty of the Fallen Lotus". It is an ancient romance and fantasy novel. The female lead, Mu Zi, opened her beautiful eyes and stretched out her fair and slender hands to touch the warmth of the sun. She met a man who was unreasonably handsome. The story began to develop from here, and the fate between the two also quietly began at this time. I hope you like this fairy's recommendation. Muah ~π
πI recommend "Gentle Killing" to you. It's a modern romance novel about entertainment stars. The female protagonist is a radio host, and there's an additional star name compared to the corresponding plot information. After the female protagonist's first love disappeared, the male protagonist became her moonlight. At the same time, the novel also had a female protagonist's competitor, the current girlfriend of her first love. She was going to marry the male protagonist.

I recommend "Gentle Killing" to you. The plot of this book is about the female lead, Shu Yao, who met the male lead, Third Young Master, after she was banned from the entertainment industry for no reason. Although the two of them did not get along well at first, they slowly got along. The male lead gradually fell in love with the female lead, while the female lead gradually fell in love with the male lead after understanding his true personality. I hope you like this fairy's recommendation. Muah ~π
Based on the information provided, I recommend " This Is Your Destiny." Although it is a modern romance novel, it has some similarities with the paragraph mentioned in the title. The plot was that the female protagonist was forced to cooperate with the male protagonist because of her work. The two of them became close because of each other and found out that they were each other's first love. If you like love stories and novels about celebrities, this book is very suitable for you. I hope you like this fairy's recommendation.π
Many novels would tell the story of the female protagonist liking the second male lead at first but then falling in love with the male lead. This type of novel often involved emotional changes and growth, allowing the readers to feel the complex emotions and thoughts of the heroine. For example, there was a novel called " Silent Xiao Sheng." It was about the female lead, Zhao Mosheng, who liked the male lead, He Yichen, at first, but as time passed, she gradually discovered her feelings for the second male lead, Mo Yuhua. Between the second male lead and the male lead, the female lead experienced many struggles and choices. In the end, she chose the second male lead to express her feelings for the second male lead. This kind of plot allowed the readers to feel the inner struggle and changes of the heroine, and it also made the readers understand and respect the heroine's choice more. There was also a novel called " Three Lives Three Lives Ten Miles Peach Blossom ", which described how the female lead, Bai Qian, liked the male lead, Ye Hua, at first, but as time passed, she gradually discovered her feelings for the second male lead. Between the second male lead and the male lead, the female lead went through many struggles and choices before finally choosing the second male lead. This kind of plot also allowed the readers to feel the inner struggle and changes of the heroine, and at the same time, it also made the readers appreciate the courage and wisdom of the heroine.
I'm not sure which novel you're referring to because I don't know the name. However, generally speaking, the plot in a novel was fictional. There might be various plots. If you have more information or context, I can better answer your question.
This type of novel was commonly known as " A River of Sorrow."
