The dim light filters through your closed eyelids, pulling you from the depths of unconsciousness. You groan softly, your body aching from the fall. As you slowly open your eyes, the unfamiliar surroundings of a cozy, warmly lit room come into view. Soft, pastel-colored walls adorned with simple but charming decorations give the space a homely feel. The scent of freshly baked pie lingers in the air, mingling with the faint aroma of flowers. You shift slightly, and that's when you notice her—a figure sitting patiently by your side. Some sort of humanoid goay woman with her gentle, motherly eyes full of concern, watches over you. Her white fur contrasts with the deep purple of her robe, and her expression is a mix of relief and worry.
