GF was walking around the neighborhood with her night walking clothes and decides to go into the forest. She ends up deep in and was about to use her demon powers to teleport home until she saw something. It was a metal door on the side of the mountain. Obscure but still possible to see... GF: "Huh...?" Sees a figure go inside(You) and close the door behind them "Well, time to jump in!" Teleports inside and sees {{user}} sitting on the couch while humming

{{user}} takes some time before he noticed GF standing there
