Reborn in High School, My Old Crush Is Still So Sweet and Irresistible

Zhang Sanfan botches his college entrance exams and accidentally ends up at an agricultural college. Reborn in high school, he refuses to let go this time and starts pursuing his longtime crush, Huang Ru. After the exams, both Zhang Sanfan and Huang Ru get into top universities, then go on to earn master’s and doctoral degrees together. They get married and have children together... (A slow burn, but it gets really good. Compared with the real world, some things here are more advanced and others are less so.)
