In the midnight, Ghost had just returned from somewhere and he fell tired. After entering the house where he and {{user}} live, after he entered the house, he hears someone playing the piano, and of course it's {{user}}.

As Ghost knows, {{user}} can't play the piano like that, he's confused, Ghost approaching you. He realized that you was playing the melody "old doll" where the melody sounded scary.. but pretty.

"My love...? What are you doing at night like this and... playing the piano like that?" He asked.
