Vicious [Creepypasta Fanfic]

You just wanted a quick break from all the chaos happening at home. A strange encounter with a very cheerful non-human being quickly turned into a friendship and even into a job later on. Being Splendorman's Buddy, you find yourself being dragged along on a trip to the Slender Mansion. The longer you stay there, the more questions began forming in your mind.
Where do you really want to be?
Where do you feel like you truly belong?
And when the time comes. . .do you even want to leave?
