Can you recommend some romance novels? It would be best if there were two?

I've read it before, but I don't remember the title. I really want to look for it again. Who knows the title of the book, the author's name, or the protagonist's name? This way, he could find the book. Thank you very much! (1)It was about the heroine's mother passing away when she was young and living with her father. Her family was quite rich. When she graduated, she liked a man in an advertisement and told her father that she would marry the man in the advertisement. As a result, her father and the man's parents were family friends, so they arranged for the female lead to live in the male lead's house. The male lead actually owned a company and was just helping a friend to make a cameo in an advertisement. The female lead stays in the male lead's house. The male lead's family had all gone on a vacation under an excuse. The nanny also asked for leave. So it's always been two people The female lead was very muddle-headed. She couldn't do anything well and even burned the kitchen when she cooked. Anyway, there was a lot of trouble, and in the end, it was always safe. It was as if her mother was blessing her from heaven Another time, the heroine's father wanted to take her to a banquet and introduce her. Then, the male lead and the female lead wore a couple's dress and picked up the female lead halfway. In any case, the male and female protagonists would be together in the end. (2)The story was about a female protagonist meeting a male protagonist in a bookstore. Both of them wanted to buy the same book, but there was only one left. Later, the heroine met two other men. One was the man her friend liked, who played the piano. I can't remember the other one. Of course, in the end, she still ended up with the male lead. She remembered very clearly that the new house prepared by the male lead was painted pink in the small villa. There were ivy outside the wall. The male lead's home phone number was 257 or something, Love My Wife. Also, the heroine's family was very rich. It seemed that her father was in a toy company, so she had a lot of cute little girl toys. In the end, she set her friend up with the man who played the piano. She almost married another man because she wanted to anger the male lead. Later, the male lead had been waiting outside her house in the rain to explain to her. When he left, he drove too fast and got into a car accident. Of course, everyone was happy in the end. I really want to look for it again. Does anyone know what the name of this book is? Or the names of the male and female protagonists. That way, you can also find them. Thanks! Does anyone remember the title of this book? Thank you. I can basically confirm that it's not Xi Juan's, not Zuo Qingwen's, not Pengyu's, not Jian Ying's. He didn't know anything else. If it's Xin Zimei's, it's not good. I guess I can't find it Thank you!
