Lin Weiyu and Shen Chaoyang's warm long run from campus to wedding dress. In high school, she was the stable and number one academic, and he was a young man who was partial to subjects but had amazing talent. They became roommates, agreed to take the exam for the same university, and planted the seeds of love in the pile of test papers. When they were in college, they faced the test of different majors and being in a different place. They used a "love agreement" to protect their relationship and jointly planned to study abroad. During their years at Stanford, they supported each other in foreign countries and each emerged in the fields of artificial intelligence and computational economics. After returning to China, he became a professor at Tsinghua University, and she took charge of the financial technology laboratory, eventually ushering in the birth of twins. This is a story about mutual achievement - there is no bloodshed or misunderstanding, only two hearts that are always on the same frequency in time. The joy of youth is written into dependence for the rest of life, and love flourishes as they grow together.
