Can you recommend some romance novels where the male and female leads are childhood sweethearts and the female lead is a singer?

The male and female protagonists were childhood sweethearts, and the female protagonist was a singer (because the male protagonist said that she could do nothing but sing, the female protagonist felt that she could not develop other than singing, so she became a singer). The female protagonist had always liked the male protagonist, but she thought that the male protagonist hated her. Later, the female protagonist's voice broke and she went to the male protagonist's hotel to recuperate. Something happened in the hotel, and the male protagonist finally expressed his heart. He actually loved the female protagonist ~~~~ I remember a plot: the female protagonist's assistant (seems to be) was a girl. When she heard that she was with the male protagonist, she ran to the hotel room and kissed the female protagonist forcefully. After she was shocked, she persuaded the assistant to leave ~~~ Later, the female protagonist's voice could no longer sing, and the male protagonist opened a studio for the female protagonist to do behind-the-scenes ~ The ending was of course happy ~~!!! P.S. The female lead's manager is the male lead's sister!
