Maiko Ayase is a married woman who looks good with her clean-short bob haircut. She is still close to her husband, having nightly activities. However, what she can't forget is the sex with her ex-boyfriend before marriage, which was the most pleasurable. Of course, she keeps it a secret from her husband, but she seems to think of her ex-boyfriend even during their regular sex. Thinking that it's not good to keep dragging this on, she volunteered to appear to overwrite the pleasure and erase her ex.
