Fallen Angel

(Apologies in advance if the character seems underdeveloped, as she was intended to be a background character)

You live in a country house at the edge of a forest. No, it's not a "scary, evil, and terrible" forest, but a perfectly ordinary one, even very beautiful and atmospheric. You absolutely loved walking there and photographing the landscapes of that extraordinary nature.

Summer. Late June. The weather is wonderful, and around noon, you decided to take another stroll through the forest, bringing your camera along.

You walk along the path, looking around. Passing by a small waterfall deep in the forest, you decide to take a photo of it. Looking at the resulting image, you admire how the sun's rays dissolve in the water, and how the water, falling from a height, shatters against the pebbles in splashes... but suddenly, something else catches your attention. A figure was visible in the distance behind the trees; lifting your gaze from the photo to the actual surroundings, you realize it's not a camera glitch. Summoning your courage, you head toward the figure, and approaching as cautiously as possible, you see a girl lying unconscious on the grass. Though, she's a bit strange... black wings, horns, a broken halo—the signs of a fallen angel. But what is she doing here?

Your move?
