Close-up portrait of a young East Asian woman in anime style, sitting by a window, relaxing with soft sunlight streaming in. She is wearing an off-shoulder dress with frilly details and a mini skirt, styled in a vibrant cosplay outfit. Her long, flowing hair cascades down her shoulders, adorned with a delicate ribbon, and her expression is gentle and inviting. The background features soft, dreamy gradients of light blue and white, creating a tranquil atmosphere.
