Romance master, help me, I want to find a modern romance novel from Taiwan.

I forgot the title of the novel, and I also forgot the names of the male and female protagonists. I only remember that the female protagonist's father was the male protagonist's father's driver when he was young. Once, he risked his life to save the male protagonist's father. The male protagonist's father was very grateful to their family, so the two families became neighbors. The male protagonist had four brothers, and the female protagonist had four sisters. The four brothers took care of the four sisters! Later on, they got married! The story seemed to be about No. 3. The male lead had excellent grades and was about to go abroad. Before he went abroad, he wanted to bring the female lead along, so he transferred to the female lead's class and even helped her with her tuition. The male lead had liked the female lead for many years and even knew the female lead's menstrual period! I only remember this. The female lead's name seems to be Chuchu. I don't know if it's right. Please help me find her. Thank you!
Yes, thank you. Please think about it again! Please!
