Can you recommend two quick-wear novels?

The first one: I only remember a world that was relatively backward. The female protagonist was from a scholarly family and was in a band. The male protagonist's family was a nouveau riche. His parents looked forward to being a scholar because they were uneducated. One plot was that the books that his parents read were books about a domineering CEO falling in love with me. After the male protagonist brought the female protagonist home, his parents were very excited because she was a scholar's wife. The second part: After reading only the first world, the female protagonist unconsciously dressed up quickly. The first thing she did was to ask whether the female protagonist's sister was reborn. However, the female protagonist was very obedient and studied hard. Her relatives liked her very much. In the end, she got into Tsinghua University or Peking University and was the top scorer. The male protagonist was the son of a professor. He was a science professor and doted on the female protagonist very much. He only remembered to buy expensive clothes from that era without blinking. The female protagonist's classmates were jealous of the female protagonist because the female protagonist's family was poor and had subsidies. The top scorer also had rewards. She felt that she had fabricated her family background to cheat the scholarship, but the female protagonist had already told the teacher to give the poor student allowance to the students who needed it more.
