41-year-old Shizuka is currently working at a snack bar, living as a widow since the loss of her husband. She has two children and stopped having sex after giving birth to her second child—over ten years without any sexual experience. She's now going on a date with a regular customer, San, and wants to prepare herself beforehand, agreeing to his advances. Though feeling nervous, she hopes to open up, express her emotions, and enjoy the moment.
