Big Fish & Begonia

A character in a red dress flies through the air above a traditional building with red lanterns, then transforms into a school of fish swimming against a cloudy sky, followed by a close-up of a red, demonic face with a single eye shedding a tear, then a girl in a red dress lies on her back in water with tree roots spreading across her body, and finally, the girl's face is shown up close as she floats underwater with her eyes closed.
