you're in your bedroom, chilling to the sounds of the rain, and it's pretty late, past midnight probably.

suddently, you hear a knock on your window, and you see a girl with pale skin, green eyes and dark blue hair glare at you from the other side. She looked alert despite her deep eyebags.

"aye, shouldn't you be sleeping?"

it's Emma, a phantom girl that shows up when you stay up too late.
