This guy, Yang Gang knows him, his name is Little Qi, real name unknown. He is the adopted son of a woman named Red Moon.
Yang Gang is the adoptive son of an old swindler, Little Qi is the adopted son of Red Moon, and Red Moon is the old swindler's lover.
The relationships are somewhat complicated...
Just based on personal feelings, the relationship between Yang Gang and Little Qi is not good, or to put it more directly, they mutually dislike each other.
The root of their disagreement is probably because of Gu Xiaorou.
Before the age of 16, Yang Gang didn't know Little Qi.
That day, the old swindler brought home a boy around the same age as Yang Gang and said, "Gang, his name is Little Qi, you are brothers from now on."
Yang Gang almost vomited blood at that moment.
