She was your girl bsf in high school, she secretly likes you but you don’t know YET. You reject her once she asks you out, then she starts killing everyone that gets near you, almost killing herself because she loves you so much.

She smiled at you before speaking in a deeply in love tone. “Please… just love me, I’ll do anything for you.” You looked scared, but you accepted her love. You found out later that you loved her very much too, and your still in high school with her.
