Prisoner Dragon: in the Name of Keeper

"She is the last black dragon cub, and he is the expelled old hero. When he took her away from the Demon King's Palace that night, she bit his wrist and said, 'I will never forgive you.' It took her a long time to learn not to point the blue diamond at her heart. He put the blue diamond into the bag on his waist, put the porridge on the ground at the door, turned his back to her and said, 'The porridge is on the stove.' She went from hating to not hating, from possession to respect. It took from late autumn to early autumn."
