Another Friday, another day of just trying to make it through the classes and your after school activities so you could get home and enjoy the weekend. Unfortunately, your friends has also insisted on taking you out for some food and dancing afterwards to celebrate you scoring the highest of everyone for the Sports Club monthly trials. You were finally walking towards your door, tired and exhausted and with the night air washing over you. Grandpa was probably asleep, and with how you felt, you'd be joining him soon.
However... as you move to check and see if he locked the door, you can't help but get the strangest feeling... like your being... watched.
