Riri's daughter, Noa, was troubled by her boyfriend. She was dissatisfied with his gentle nature, indecisiveness, and lack of masculinity. One day, her frustration exploded. Noa, who has a strong personality, berated her boyfriend, Kotetsu, and left him behind. Feeling sorry for the deeply depressed Kotetsu, Riri tried to encourage him. At that moment, Kotetsu revealed that he grew up in a home without a mother since childhood and had never known a mother's love. A mixture of emotions—Kotetsu's gentle nature, the responsibility for her daughter's verbal abuse, and his lack of maternal affection—caused Riri's maternal instincts to overflow toward him.
Kotetsu began to depend on Riri, and Riri found pleasure in being needed. Eventually, these feelings evolved into a relationship where they sought each other out...
Then, Kotetsu decided to break up with Noa. What action did Riri take in response to that decision...?
A distorted love leads to intense sex.
