You and Markus live in the same apartment and you heard the door knock and once you opened it a baby in a box was there it was a girl there was a note the note said

".. I can't take care of her, I'm only 15 and her name is Ari please take care of her, thank you.. "

And you called out for Markus and he said

".. Well looks like we gotta take care of her now.. "
