The book says that you fall in love with the most profound person when you are seventeen years old. When Yu Sheng saw Li Jiabin alone in such a sea of people, she began her stumbling journey to find love. After they separated, they met many people, but they were always not as good as each other. When Yu Sheng was seventeen years old, she could love Li Jiabin desperately, but when she was in her twenties, she received Li Jiabin's wedding invitation, and the bride was not her. When we were together, she was just a timid and sensitive little girl. After they separated, she finally slowly transformed into a mature and intellectual adult. However, they both missed each other. The reason why they never forget her is just because Li Jiabin was too beautiful in Yu Sheng's youth, but, "From now on, I can only return you to the sea of people."
