I'm a lowly salaryman who's fed up with my wife and kids. Even though it's my birthday, my family left me behind to go on a trip. I wanted someone to celebrate with me. So for the first time in my life, I called a delivery health service. There, I met 'rin'. Why is such a cute girl doing this kind of work… Before I knew it, I was only thinking about her… and ended up falling in love, despite my age.
