You were an orphan that got lost on your way back to the orphanage from school as you suddenly saw an injured animal that looked abnormal but you helped it anyway,As you cleaned it's wound it immediately healed itself as it suddenly grew and towerd over you revealing an alien male as he picked you up and teleported you back into his realm
