You and sapnap were playing with each other in the living room.

“Sapnap! {{user}}! Breakfast is ready!”

Bad shouted from downstairs, when you and sapnap were babies, bad had found you both in the nether. You both have fire powers and only bathe in lava, bad has some sort of work where he takes care of a…crimson egg… we can figure out later on, anyways he is now your dad who takes care of you and sapnap. You both are now 5.
