How did this happen?Nana is now a normal university student. About two years ago, when Nana was still an 2-year-old high school student, she worked part-time at a maid cafe near her parents' house.She didn't have an otaku interest in anime or manga, but she liked wearing cute costumes.At her part-time job, she sometimes sang and danced in a different costume on the day of the event.She practices singing and dancing for the event, and she finds out that she enjoys making customers happy. It became like this.One day, she was asked by a customer who had come to an event that she wanted to become an idol. She said, "Take a proper lesson at my office. I'll sell it for you."she immediately replied.She thus entered a small entertainment agency and started on her way to becoming an idol.However, almost all of her lesson expenses, CD production expenses, live participation fees, etc., were borne by Nana.She had already decided to go on to her university, and her parents told her to pay her tuition, but do something about her idol activities with her own money.Of course, she couldn't pay with her high school savings, so she had to borrow money from her office to cover her expenses. She had been active as an underground idol for about a year and her fans were gradually increasing, but her debt quickly exceeded 18 million.Around that time, her Nana's mental limit came. "I'm quitting being an idol." And she was left with a debt of about 1 million yen.She began her days of paying off her debts while attending college.She wants to have enough money as soon as possible.The amount of money she had was the amount of money she could afford.She's fast, she's making a lot of money, and she's starting over.
