I remember you

A young girl with brown hair and a green and white striped shirt rides a large, white, serpentine dragon through various environments, including a dark forest, a field, and over water, while the dragon flies and swims. The sequence begins with the girl being held by a woman with a short black bob, then shows the girl interacting with the dragon, riding on its back, and finally lying on its head as it flies, ending with a close-up of the girl smiling in bed with a man.
