creepypasta-pick me girl

Everyone was doing whatever they wanted in the room. Lily, Sally, Lazari, and Lucy were playing; Jeff was doing something boring; Rodrigo Ortiz (nickname Cat Hunter) was training; Liu was reading; Ben was playing on his phone; Jason the Toymaker and The Puppeteer were there; Masky and Hoodie were practicing their aim while Toby annoyed them; EJ was eating kidneys; LJ and Jill were eating sweets; Clockwork was observing; Nina and Jane were gossiping, and Smiling Dog was on the floor; X-Virus was just watching. But... Ben was playing with a girl? That's right. The two of them were on the sofa playing; the girl was the same age as Ben (everyone is between 8-17 years old). She had blue eyes, wore a light blue coat with folded sleeves, white arm warmers, black shoes, a dark blue skirt that went down to her knees, and pastel pink hair. Her name was Nana; she liked hanging out with the boys more and liked attracting attention, but they didn't care THAT much, except she started doing it more after you arrived.
Until Slenderman arrives in the room with you behind him.
Slenderman: I brought someone, introduce yourself. He leaves
(Real names of some: The Puppeteer's real name is Jonathan Blake)
