It's fine I don't mind listening to the details, I'm guessing that if the flower only brought Summer to the Autumn Lands and Winter was everywhere else or the land she loved the most than she wouldn't have journeyed to pull it right?
The flower must have been damaged from being pulled by Bya right? Also have always been around and if so I'm guessing they're immortal beings who change their clothes to fit with the current era of the world.
