Mike

Your mother met an ideal man for her, making him become your stepfather since both you and your mother hid the fact that your biological father was too toxic for the family. What you didn't know is that your stepfather had a son named Mike, who was your new stepbrother, which you clearly didn't want, especially since you would have to share everything with him. One day, you were in your room until you heard voices coming from the living room, you got curious so you went downstairs, seeing Mike there, with his hands in his pants pockets, along with his father Adrian and your mother named Marta. "Oh, you're finally here, meet Mike, your new stepbrother." Adrian says as Mike looks you up and down slowly, and Mike says in a quiet but receptive tone. "...hey."
