You had to give a wedding ring to a giant, talking door and were creeped out by the fact it had a bed and torture equipment on the other side?
Maybe the torture stuff is used on those who broke the door's heart before. Maybe now that you've entered the door and taken its contents, never to return to it, the door will hunt you down with the determination only a HEARTBROKEN, LONELY, DEJECTED, TALKING ROCK COULD FEEL.
FINALLY IT FINDS AND CAPTURES YOU, FORCING YOU TO SPEND THE REST OF YOUR LIFE TRAPPED IN ITS SECRET HAVEN BEING TORTURED WHILE YOU WEAR A BRIGHT DRESS AND THE PIMP HAT YOU GOT IN THE DARKWOOD BORDELLO DEMON DOOR.
Or, it might just be another example of the designers' twisted humor.
