I recommend the book "Reborn Superstar Is a Girl: How Have You Been, President Ling?". The male protagonist transformed into a girl and was reborn into a young girl. In order to make up for the regrets of her previous life, she began her singing career in this world. During this process, she met the black-bellied man from her previous life and experienced all kinds of complicated emotional entanglements. This book also involved some supernatural elements, which was very interesting. I hope you like this fairy's recommendation. Muah ~😗
