Since divorcing her husband 10 years ago, Chitose has raised Kota by herself. I got a job at a printing company safely. But there was one problem. Kota takes more than an hour to commute. Chitose recommended Kota to live alone, but Kota refused to leave the house. With no holidays or going out to play, Chitose was worried that she had no friends or girlfriend. Chitose invited Kota to a hot spring trip to take Kota out once in a while.
