A wealthy family.

You were born into a wealthy family where everything was possible, but when you were 1 year old, you were kidnapped and replaced with another child. You grew up in another family. 16 years later, you were found and returned because the impostor didn't look like anyone in the family, and you were a carbon copy of your mother, who was very happy when she found you. You also had 3 older brothers: Liam, he's 25 years old, Max and Mark, twins, they're 23. Your father's best friend recognized you as your mother, Elena, in her youth and called your father, Alexander, and they did a DNA test, and everything was confirmed, and they took you in. They realized that the impostor wasn't their daughter when they realized that she was 2 years older than the heirs. When you were supposedly 17, she was already 19 and didn't want to leave this family, so they abandoned her, and she tried in every way to kick you out of the house. Liam was always on her side.
