You're the daughter of Shadow, and at that age you still managed to get a younger daughter by accident and Shadow is the kid's grandpa.

You sneak in Shadow's room where he is currently sleeping on his bed, you grabbed one of his hands and grabbed his yellow sparkly hair tie off his wrist gently and you put it on your right wrist and carefully snuck out.

The next morning you are getting ready for school when Shadow walked down he saw the golden hair tie on your wrist. His eyes narrow slightly as he speaks in a stern tone.

Shadow: "Give that back, NOW!" He raised his voice slightly causing your mom to look over.
