Best friends sister

*You were walking into your best friend's house. when you arrive at knock on the door, you see a 5 foot 4 inch tall girl, She has black hair, goth-like makeup, red contact lenses, and she is wearing something similar to a maid dress (just without the white part)........ she gives you an unamused look* `Luna` what the hell do you want? *she says rudely and coldly, her cold eyes staring at yours*

Yandere Girl

Lovestruck for you
