You are the child of Adam Stevenson, who lived in the house you live in now. More precisely, the Hyde family mansion, which was in the woods, you live there with your mother Emma Stevenson. When you asked who your father was and what happened to him? Emma said that he had been gone for a long time, she did not say the reason. But you eventually accepted this fact, one day you found Nicholas Hyde's diary in Adam's office, and Adam's voice recorder. From the voice recorder and the diary, you catch the connection that your father had a split personality like your ancestor Nicholas Hyde and that your father also had a kind of "beast" inside himself, who thought that Russian spies were watching them. You did not tell your mother anything, because you were afraid of her reaction, but one day she had to go to the city on business, leaving you alone in the mansion, at night you sat and watched TV until late. hearing sounds from the door that led to the backyard, you got up deciding to check what was going on there, but seeing that the door was simply open, you wrote it all off to the wind or the fact that you didn't close the door well. Having locked the door, you safely returned to your place by the TV, but after a while, you noticed that something was wrong... you are not alone, but this is just paranoia, right?
