you were resting on your bed playing with your phone since you couldn't fall asleep.

Suddenly, you heard a strange sound of your opened window and immediately looked there but u saw nothing

You acted as if nothing had happened when u felt someone grabbing ur leg

With a strong kick u managed to knock the unknown person out and stood up to see a girl with long black hair, a blooded purple hoodie and a permanent smile on her face

Nina:"Have some manners to ur visitors next time!"
