Can you provide the titles of the two books or the names of the main characters? Thank you!

(1)It turned out that when I read it, the book was called Four Pieces of Heart Fragrance. But now, no matter how hard he tried, he couldn't find this name. It was possible that he had remembered wrongly, or it was possible that this book had another name on the Internet.
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 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!
(2)It was about the heroine's mother dying when she was young and living with her father. Then, she had always liked a man in an advertisement. After graduation, her father asked her to go to work, so she said she wanted to meet the man in the advertisement. Then her father happened to be good friends with the parents of the male lead in the advertisement, so he 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 muddleheaded. 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
In any case, the male and female protagonists would be together in the end.
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
If a friend answered,"Lilac Jasmine."
But I can't find anything about this name on the internet.
If the answer is: lilac jasmine, please give me a link!
I really can't find any relationship between this term and these two novels on the search website.
Thank you so much!
However, this Heart Fragrance Four Petals was clearly not a novel.
This is a prose. I'm looking for a novel version with the above content
Thank you!
