Seeking a romance novel about childhood sweethearts. The male lead is called Min something Sheng, and the female lead is called Xin something.

The male and female leads later raised a dog called Sheng Xin. The fragments I can recall are as follows:
When the female lead met the male lead, she was five and he was ten. The male lead was sleeping on the grass, and the female lead was scolded away by him. Then, the male lead was kidnapped by a group of people and held hostage in a car. The female lead wrote down the license plate number and told her mother. The police arrived at the place where the male lead was kidnapped. The kidnappers threatened the police with guns. Later, the female lead pounced on them and shouted,"You're not allowed to bully my brother!" However, the kidnapper kicked her away in disdain. The police took advantage of the kidnapper's distraction and pulled the trigger. The male lead rushed up to hug the female lead. The female lead cried and said,"Brother, Xinxin hurts."
This was part of the beginning. It should be the introduction.
Later on, when the male and female protagonists grew up, I remember the following scene in the later part of the novel:
The male lead was injured for some reason, and the female lead was the "dating queen" at school.
Now it was the rough original text: "'Xinxin 'a shy boy asked,' What are we going to eat for lunch?'" Hmm? I was wondering if the person in the ward had taken his medicine, so I didn't pay much attention to it. En, as you wish,'I randomly agreed. (I can't remember the middle clearly) Ah, oh ~ Brother Sheng actually kissed me! (And then forgot)"
The male lead was of French and Chinese descent, and his eyes were green. The female lead was afraid of the dark. In the end, the second male lead (surnamed Xia, I forgot what his name was. The female lead met him in junior high school. He had single eyelids, his parents were divorced, and he lived alone) had his own bar. The female lead dressed sexily and went to drink. A hooligan came to hit on him. The male lead appeared, put a coat on the female lead, and stared coldly at the hooligan with his green eyes.
He couldn't remember anything else. In his memory, this novel was very good. Unfortunately, he forgot the name. Please help me recall.
