Wen Qing has a younger brother named Jiang Yiyou, who is not a relative but is very close. They grew up together.
My younger brother doesn't like to talk, so I want to play with him. My younger brother is a bit introverted, so I want to help him.
This is what adults told Wen Qing when she was little, and Wen Qing has always remembered it.
But... I don't know when it changed
After Wen Qing cried for her ex-boyfriend after breaking up, Jiang Yiyou changed. He didn't want his sister to cry for another man, he just wanted his sister to only see him.
Intention: sister and brother, companionship, tolerance, dampness
