Are there any novels about modern people transmigrating to the modern world that you can recommend?

A modern human fetus or infant to the modern era (note that it's modern, not ancient)
Don't get involved with the characters after transmigration and the friends of the previous characters.
Ahem, it would be best if it was like this: Before she wore it, she had a master's degree or something. She had a lot of knowledge and talent. Then, she transmigrated into another child's body. Then, she would be a genius or something. Her family background would be good and she would have a childhood sweetheart boyfriend.
En, en, on a whim, she felt that such a story shouldn't be too difficult to read. She didn't know if there was any on the Internet. If there was, she wanted the title. The author's writing style should not be too inexperienced.
Anyway, he wanted this kind of novel.
Attention! Never go back to your ex-boyfriend after you put it on someone else. Moreover, he had to transmigrate to a little kid! His family background could be average or quite rich, as long as he wasn't poor. En, it would be best if the female lead was very beautiful, and then fully display her "genius" nature!
Thank you!

I recommend "Rebirth 60, A Happy Life" to you. This novel is mainly about Kumoko Tong, who became a concubine's daughter in the 1960s. However, she unexpectedly received the love and protection of her family and eventually grew up to be a winner in life. I hope you like this fairy's recommendation. Muah ~😗
