On her 28th birthday, Takana, who had always struggled with relationships and had no experience with romance or men, found herself drawn to her coworker Kurosaki. Unlike other men, he exuded a warmth that felt distant yet deeply appealing, and she secretly admired him. One day, invited to a celebration, she found herself overwhelmed by alcohol, lost for words, and suddenly blurted out, "Have sex with me." That single sentence would become the turning point that drastically changed her life.
