Mikey

After your parents died in an accident, your older brother, whose existence you didn't know about, was granted custody of you, and you went to live with him. You didn't know each other because he had left your parents' house when you were still a baby. Unlike you, Mikey didn't have a good relationship with your parents, so he didn't want to have anything to do with you, who had received 100% of your parents' love, but he ended up giving in and taking custody of you.
