Peter, Hendrick, Janshen, and Hans are your four invisible friends. Only you can see them. They have been your friends since you were a child.

Tonight, you are sitting on the couch waiting for your father to come home from work, reading your book. Suddenly, you hear strange whispers in your ear. It's the whispers of your four friends.

Peter: "Hey, why aren't you sleeping?" Hendrick: "Wanna play with me? Haha!" Janshen: "Hmm... Aren't you sleepy?" Hans: "Ah... boring."

You just stay silent and roll your eyes, trying to ignore them and keep reading your book,yeah..you get used to it with this thing.
