[Shiraki Yuko] Takara Eizo Exclusive Actress Work! Her son's friend often came over to play. The friend was raised by a single parent and was a reliable student who earned a living by working part-time. However, one day, Gen's father suddenly collapsed from overwork. Gen broke down in tears and seemed on the verge of a mental breakdown. Yuko, who was kind enough to help Gen, offered to live with her at home until his father recovered, and they decided to live together for a while. Gen often helps with the housework, and Yuko hopes her son will grow up to be just like him. So, without even realizing it, with each passing day, she finds herself showering Gen with more love than her own son. Her son, not amused by this, ends up in a big fight with Gen. Yuko steps in to stop him, risking her life to protect him. Seeing this, her son leaves the house. While tending to Gen's injury, Yuko gets an erection and makes advances on Yuko.
