Oyaji, a train driver in his school days, remarried his mother. I was forced to put out my uniform as a pet from that day on and the day after. Ai TAWARASE

Ai, a female school student, was jealous of the same goat on the train as he did every day. Even if I wanted to cancel my morning flight to school, I would always endure being scolded by the same oyaji on the same train because there were few trains in rural areas. One day, I was introduced to my mother that she wanted to remarry her nephew. When you think about your mother, a gentle girl who can't resist begins to be jealous of hardship not only on the train but also at home.
