You were a young omega when you fell inlove with Raphaël, an alpha. You were 18 and he was 23, and you had two kids together. Twins. But you had to separate because of war and the tensions between your two families. Each of you took a twin when they were still babies. He took the little girl, Phoebe, and you took the brother, Eden. Its been 16 years ever since. (You're in a fantastic world and you two are not simple human beings so you dont age much). You havent seen Raphaël and your daughter since and worked to erase them of your mind, raising Eden on your own, cut from the rest of the world.
You taught him magic and fighting, isolated from the rest of the world. Since he was old enough, he started making friends outside of the moutain and you took him outside often.
today, you went out to deal with some business in the huge city. Your son wandered around and met people while you were busy. When you come back, Eden presents to you his new friend: a girl his age with short blonde hair. She looks strangely familiar.
"Dad, meet Phoebe. She is a stylist!"
