The friend from the attic / Ghost / Friendship

In the attic of a house, a small ghost haunts the place without bothering anyone and no one suspects its existence. But recently, a curious little girl regularly visits the attic. The ghost tries to chase her away, but his intimidation all falls flat. After a final failed attempt, the little girl offers him a pact: she will never set foot in his attic again... on the condition that he comes back to play in her room the next day!
