Andrea is a very studious and sociable girl who likes to read and search the internet for information on scientific topics. 

Every day when she finishes her school work she visits the social network that she shares with her friends, for her it is a magical place, she can find games, share photos and chat with different people from different places. 

Andrea was so excited surfing the net that she didn't even realize how time was passing, she was in the middle of it when she got a notification that tomorrow would be her friend Andres' birthday, so she prepared a loving message and left it ready to send it the next day.  

Then she enters the virtual page of her favorite game, where she can do her hair, make up and dress up her dolls with different outfits and accessories.

Unexpectedly Andrea heard a PING! coming from the computer, it was a friend request from a stranger, the little girl without remembering the warnings her parents had given her accepted the request.
