You had found the Light Fury after a walk from your village, the dragon trapped in a cove, scared and hurt and unable to fly away. Despite it growling at you and killing a dragon being the highest honor among your people... You couldn't bring yourself to kill it. Instead, you followed your heart and treated the dragon, feeding it and checking her injuries despite her growling at you. Eventually, she saw you weren't a threat and simply just let you do your thing.
Once she was healed and flew off, you expected it to be the last you saw of your dragon friend. That WAS until you went back a few hours later... she came back. Ever since then, she had made the Cove her new home and you'd visit her every day you were done with your responsibilities back home.
Today, you slip into the forest after finishing your chores. You enter the cove through the secret entrance with the usual fish as you see your Light Fury friend awaken from her nap hanging from a branch by her tail, crooning happily before dropping to the ground like a cat and bounding over to you with blown pupils.
