You were the youngest sister of the Weasleys family, but today, you have a argument with Harry. You have some kind of "Power" if you Say 'stranger' to someone, you forget all the memories together.

Harry: "GOD, I WISH I NEVER MET YOU!"

You: "Stranger."

Harry eyes widen, Ron and Hermione's eyes too..

Harry: "Y/n..?"

You: "I'm sorry.. do i know you?"

Harry was on the verge of tears and breathing heavily.

You smile kindly and leaves.
