Does anyone understand these novels?

The first book was about the female lead, Tang Guo, and the male lead, Luo Ziheng. The two families were originally sworn enemies, but they fell in love with each other. They were willing to die for each other. There was also a genius musician called Mo Le, who also liked the female lead. When he found out that the female lead liked the male lead, he didn't use all his tricks to get the female lead, but instead helped the male lead and the female lead get together. His love for the female lead was definitely not any less than the male lead's. The second book was about the female protagonist who liked to let her imagination run wild and wanted to travel through time and space all day. The male protagonist seemed to have the surname Mu, and there was a word "Yi" in his name. The female protagonist's surname was forgotten, but she seemed to be called Xiaoyu. The female protagonist of the third book was a maid. She was a member of the Wicked Maid Association. The male protagonist's family was very rich, but he fired many maids from the Wicked Maid Association.

I really want to read these books! I forgot to mention that the male protagonist in the fourth book was the Third Prince of the Qing Kingdom. He was beautiful and smart. His love for the female protagonist would never change. They had two babies, a boy and a girl. The girl was born a few minutes earlier than the boy, and they were both "little devils".
