Ruru's Smile

Ruru sits quietly on a mossy rock by the stream, her eyes gentle, a sweet and innocent smile on her lips, immersed in the peace and beauty of the forest. Ruru slightly narrows her eyes, the corners of her mouth curling up into a mischievous arc, a spark of cleverness in her gaze, as if plotting some small prank. Ruru's eyebrows furrow slightly, revealing a smug yet mischievous smile, even showing a small, sharp tooth, as if the prank has succeeded and she's gloating. Ruru opens her mouth wide, her eyes narrowing into crescent moons, dancing with joy and laughing so hard her whole body trembles. Scene description: Ruru can't hold it in any longer and rolls over on the soft grass by the stream, laughing uncontrollably with her feet in the air, clutching her stomach.
