Three years into her marriage, Kanade Riko struggles with the anxiety of being unable to conceive. When her father-in-law offers to listen and help with her concerns, she opens up to him, unaware of his true intentions. Rather than offering support, he begins exploiting her vulnerability, using her infertility as an excuse to subject her to repeated sexual harassment. One day, he tells her, "Let me give you a massage that's great for conception," and forcefully pins her down. He then meticulously massages the most intimate areas of her body, indulging in the sensation and pleasure it brings him. This shocking series of events leaves Kanade deeply traumatized.
