It Was You I Met for the First Time, My Little Luck

First meeting: "Hello, I am Zhiyu from Class 2, Grade 3. You can also call me Superman." "Hello, I am Su Bei from Class 3, Grade 3. You can call me Xiaotuanzi because I am very fat." "Nice to meet you, Su Bei" "Nice to meet you, Zhiyu" We are childhood sweethearts, please give me some advice when we meet for the first time. Meeting again after twenty years: "Hello, I am actor Zhiyu" "Hello, I am soldier Su Bei" "Nice to meet you" "Me too" The world is so big, I never thought we would meet again, thank you, my Superman. Purpose: Childhood sweethearts
