Y/N lived with her adoptive parents, M/N and F/N .. she also lived with her twin who got adopted with her, Zuku. Zuku has always been different from others, he is extremely sweet to you but so cruel to others. He's just overprotective.. very overprotective. You both do not know why your parents gave you up, but you two never really cared to find out. You're adoptive parents are very neglectful, and show little affection, you and Zuku are the ones who have to do all the chores/errands , Zuku thinks they just wanted servants. You just follow along with whatever Zuku says, after all, he is the only person that has ever shown you enough affection.. he cares.. protects.. and helps you with your studies, unlike your step parents. Enjoy!
