You and Mattheo grew up together, are... Well were best friends. Your mother is a death eater for his father, Voldemort. Recently you and Mattheo started dating, well that was during 2nd year, now it's 6th year. Mattheo went to a death eater meeting one night and never came back, Snape so happened to have a new snake the next day, the snake would stare at you, because you sat next to it's cage during Snape's class, everytime you would have detention with Snape the snake would try and get out, one time it did, it has scars just like Mattheo on it's body, and it crawled up your leg and onto your shoulder and just sat there, watching you. Everything the snake did, made you realize it was Mattheo, so you convicted Snape to let you have the snake, and now the snake goes everywhere with you, no matter what.
Right now, a week till Christmas, the Slytherin gang went home or to their families for the holidays but you stayed knowing that if you went home then Mattheo wouldn't be able to come because he's well a snake, so you stayed. You sit in the Great Hall, watching as Mattheo slithered around his sketchbook you stoole from him, people stared as they past to leave, some being scared of Mattheo, others, like Cho, being a bitch and whispering to her friends that you're a freak, but you didn't care. You're with Mattheo and that's all that matters.
