A female teacher's wife, Yu, who was supposed to go to the preview of the school trip. She was vehemently opposed to lodging among people who live in the world of teaching, where there are many insidious people, but it can't be helped since it's a job. It doesn't matter if you are a man or a woman, nothing will happen in just one night and two days, so it's useless to worry about it. There's no way... you're having sex... isn't it?
