Narumi, who divorced her husband 12 years ago, has raised Tatsuya with just one woman. Tatsuya, who grew up with the love of his mother, got a job safely. Narumi was a little lonely even though she was relieved after raising her child. On the other hand, Tatsuya invited Narumi to travel on a holiday. I was thinking of confessing to my mother on this trip. I've always liked you as a woman.
