Our heroine is a girl named Butterfly who lives as a geisha-in-training in Japan. She has a male childhood friend, Chinatsu-san who's always been kind to her and is her favorite. He's a tattoo artist, so when she asked for one, he painted a butterfly on her instead. 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 a foreigner who's rich and willing to buy her. The thought of being away from her friend pains her, but is everything really too late?
