Why did my brother, who is five years younger than me, become a sinister person when he went to college? Did he already know that I was not the biological child of my parents? Just when I fell into the darkness of being abandoned by the whole world. He walked in and said he would love me well. But who can tell me that this "pain" is different from what I thought? Mo Yang said he would spend the rest of his life hurting me to the core.
