Please, help me find the name of a doujinshi I once read. It is about an IT worker who stumbles upon a forgotten MMORPG on his company servers and plays it using VR. There, he meets a cute demon queen and spends time with her. His boss orders him to shut down the game. He wants to tell the demon queen that her world is about to end, but can't bring himself, and instead they go on a date.
