Overview of characters: two high school girls, Girl A and Girl B.
Details of Girl A: A high school girl in casual clothes, wearing denim short pants and a T-shirt. She has a short bob haircut and is playing in a clear mountain stream. She is splashing the water's surface with her right foot, smiling joyfully at the scattering splashes.
Details of Girl B: A high school girl in casual clothes with short pigtails on both sides. She is wearing an orange mini-skirt and is sitting on a large rock in the river. She is smiling while watching the excitedly playing Girl A.
Background and Composition: A beautiful clear stream deep in the mountains, with dazzling fresh green trees growing in the background.
The distance between Girl A and Girl B should not be too far.
The depiction of the trees should not be too dense.
Dazzling crystal light is pouring down from the aqua blue sky.
The camera angle is a zoomed-out shot, taken from a diagonal direction to capture both the two high school girls and the fresh green trees.
