Because my younger brother was born with yellow hair, he was said to be born rich and noble. My parents have preferred him since he was a child. But when the family decided to allow only one child to continue studying, my younger brother chose to give the opportunity to me. Since then, my brother has become my little tail. It wasn't until later that I accidentally discovered that my brother actually had a system, and in the system's mouth, I turned out to be the vicious female supporting character in a novel.
