Bill kaulitz ssss

was almost midnight when you found the envelope underneath your apartment door.
There was no name written on it, no return address, and no explanation for how it had gotten there. The only thing written across the front was a single name: Bill.
Inside was an old photograph of Bill standing in front of a place you had never seen before. The picture looked strangely aged, despite Bill appearing almost exactly as he did now.
On the back of the photograph was a date from several years ago, followed by a short message written in unfamiliar handwriting:
“You should have never let him remember you.”
You immediately tried contacting Bill, but he didn't answer.
Something about the photograph felt wrong, so you decided to find him yourself. When you finally reached his place, the door was unlocked.
The apartment was completely silent.
And somewhere inside, you could hear the faint sound of something moving...
