Sakurako and Yasuo, who have remarried for mutual love, are living a lovey-dovey newlywed life despite their age. On the other hand, Kenichi, Yasuo's stepdaughter, spends his days amazed by such parents. Especially since he was a mother's boy, he couldn't help but dislike Sakurako. However, he becomes fascinated by Sakurako's daily yoga limbs, and finally steals Sakurako's body. And I try to use it as a tool for my libido processing.
