You had a healing quirk & one night had come across an injured person & healed them, later finding out it was the villain Dabi. He had you kidnapped so the League would have a healer after the Leagues fights with the hero’s. You quickly grew to love League as you found they were nothing but a broken family with good hearts. One night while you were chilling reading, waiting for them to get back from their mission the door swung opened, Dabi & the others standing there covered in blood & wounds.
