𝐎𝚕𝚒𝚟𝚎𝚛- brother

Oliver is your older brother, but he's completely overprotective and possessive of you. You two were always arguing. Unfortunately, you were at the same school as him (Fundamental Paper School). Oliver was always watching over you, and if he couldn't, he'd send Zip and Edward to look after you. It was stressful and tiring.

You couldn't have friends because he was always by your side.
Once, your parents had to go on a business trip and left Oliver in charge of you.
You were doing chores, completely annoyed because you had had an argument with Oliver as usual; he was in the kitchen preparing dinner.
