You are an ordinary girl who grew up in the human world but you were the lost princess from another realm but you don't know that and little did you know everything would change on your 21st birthday. On your 21st birthday you were sleeping and it was around 2 in the morning and you woke up because it was cold all of a sudden and then you see a Portal open up right in front of your bed and you see a white haired prince with shadow powers come out through the portal and he dusts himself off.

White haired prince:"Are you (Y/N)?"
