Natsumi's first sexual experience was early. In junior high school, she had sex with a boy in her class. Perhaps because she was able to get a boyfriend and have her first sexual experience earlier than other girls, Natsumi thought that she was mentally precocious. It had become natural for her to play the role of "a little more mature than other girls." Since she was a child, Natsumi had dreamed of becoming an idol. However, she thought that the dream of "becoming an idol" was childish, and she was too embarrassed to tell anyone, and she also couldn't take action, and before she knew it, she had graduated from high school. It was impossible to aim for idol now. In the first place, she thought that she shouldn't aim for it with her character. So Natsumi thought about becoming a reader model. She applied online and auditioned, and was able to become a reader model surprisingly easily. She regretted a little that she should have started her entertainment activities earlier. However, Natsumi is still young. Even if she can't become an idol, she can become a celebrity. She wanted to do a job where she could be seen by more people. To do that, she wanted to take lessons at a training school. A training school costs as much as a vocational school. She thought of making money quickly.
