I saw the male protagonist playing in the swimming pool. Later, they accidentally fell in love. I want to find a similar novel. Do you have any recommendations? Were there any novels with similar plots, where the male and female protagonists who were childhood sweethearts met in the same villa and gradually fell in love? I once read a book where the male protagonist often played in the swimming pool while the female protagonist often peeped through the window.

When she entered the male protagonist's bedroom, when someone bullied the male protagonist when she was young, the female protagonist would use her small fist to block the male protagonist and use her small shoulder to carry him. From then on, the male protagonist liked the female protagonist. The female protagonist's father was a policeman, while the male protagonist's father seemed to be a pianist. The female protagonist had always been the kind of carefree and slow to react. Later, the female protagonist went abroad to study. At the beginning of the novel, it was said that the female protagonist came back from studying abroad. Then, they began their love journey. Actually, the female protagonist liked the male protagonist from the bottom of her heart. She just didn't know about it. However, she finally understood. She and he ended up happily together. Have you read this novel? Can you tell me the name? Thank you ~
