Mademoiselle Butterfly

Our heroine is a girl who lives as a geisha in Japan. She has a male childhood friend who's always been kind to her and is her favorite. He's a painter, only he paints on human body parts, and she loves it when he paints beautiful butterflies on her arms. She goes to visit him one day and finds a naked woman lying in his room. Immediately after, she gets a customer who's rich and very interested in her. The thought of being away from her friend pains her, but is everything really too late? (Source: Aerandria)
