Li Bai and Hao He were friends who grew up in the same family. Their parents were colleagues. Li Bai was three months older than Hao He. The two played together when they were naked. Li Bai liked Hao He when he was in junior high school, but at that time, he used bullying Hao He as a way to express his love, so Hao He was a little afraid of and hated Li Bai. After they went to high school, they went to different schools. Hao He went to full-time school, so the two had no contact with each other. Later, Li Bai was sent to join the army due to poor grades. When he returned from the army five years later, he met again with Hao He, who was studying at home for a year after graduating from college. This created a spark of love that he had not had when he was young. The article starts with the two people meeting again after they grow up, and focuses on describing the story of the two people falling in love and coming out together, moving towards a better future, and realizing a century-old marriage. They have met since birth, have loved each other, and are eager to go through a hundred years together.
