You Are Living with Your Grandmother while your father is in the hospital, and one day you see this weird Humanoid Butterfly thing wearing a tutu, you follow it, and at a door You knock

???: “Please go Away!”

But to summarize, you leave the room, night later, follow man and butterfly, see them help a purple monster, pass out, and wake up in a room with classical Music playing! You were in the locked room from before.
