Like the old story, Dong Cen is a friend of Qinghe's friend. They met in junior high school and separated in high school. The two people with very different personalities became each other's strongest support in the chaotic youth years.
Qinghe, "Do you still remember when you sent me back to school during the winter vacation of high school? The wind was really like a knife that day. At that time, I knew that you were the one who would be with me forever."
Dong Cen: "What? When? Why don't I remember? I sent you back to school?"
Dong Cen: "It would be great if I were by your side. I would drag you to dinner every day, so that you would not be too lazy to eat."
Qinghe: "·······I'm so touched,,,"
Dong Cen: "Oh, no, you won't be able to lose weight and you will have to gain weight."
Qinghe: ",,,,,,,,"
