HMN-433 The female student works part-time to earn money for entertainment

Female student Ai is sexually harassed by an old man on the train almost every day. Even when I wanted to change my morning commute to go to school, I still had to endure being harassed by the same old man on the same train because there weren't many trains in rural areas. One day, my mother introduced me to someone who wanted to remarry. It turned out to be that perverted old man, and the series of continued sexual advances began.
