When Bai Lin was four years old, his mother brought back a little boy. His mother told him that this was his brother Bai Xu.
Maybe it was because he was too young that he stumbled and called "brother"
As he grows older, Bai Lin seems to have other feelings for his brother.
"Brother, I like you"
"Brother, I also like Xiao Lin."
Brother, will we meet again?
Will
Intention: reality
