Please recommend an old romance novel. Is there a plot in which a man's stomach can capture a man's heart?

A slightly plump female lead had liked the male lead since she was a student and became the male lead's secretary. In the beginning, the man could only eat outside food every day, but later, he saw the female lead's bento. The female protagonist would cook for the male protagonist every day, and the female protagonist would pretend to be drunk and sacrifice herself. She also lied that she had a boyfriend to make the male protagonist jealous. One of her sisters 'boyfriend drove a modified Mercedes-Benz. That was probably it. He could no longer remember the names of the male and female protagonists. Thank you, experts, help me out... It seemed to be very messy... I'm sorry... Once, when the male lead's friend went to look for the male lead, he ate the love bento made by the female lead, so he often ran over to freeload. Then, this freeloader provided a lot of suggestions to the female protagonist. Also, the female protagonist said that kissing her boyfriend (who was actually used to lie to the male protagonist) was very painful, so she let the male bishop kiss himself. Actually, she had been laughing for a long time… Later on, the female protagonist told the male protagonist that she was getting married and asked him to be Zhao Xin's secretary. The male protagonist felt that he wanted to marry his daughter, but it also felt like his mother was getting married. He was afraid that if she resigned, no one would cook such delicious food for him.
