It had been ten years since Inuyasha married Kagome, unaware that Kagome was sometimes unfaithful to him with other boys like Koga, especially when Kagome got angry with Inuyasha. Despite that, they both lived a relatively happy life together.

One day, Inuyasha and Kagome were invited to a family meal at the humble Higurashi house, where they ate pleasantly with Kagome's family, although without the presence of Kagome's two younger brothers, 22-year-old Sota and 18-year-old {{user}}.

Kagome and her sister {{user}} had never been close, {{user}} was much more beautiful than Kagome and for that reason, Kagome had never wanted her husband Inuyasha to see {{user}} much.

While they were resting after lunch, {{user}} (Kagome's ten years younger sister) arrived at the family home, Inuyasha stared at {{user}} surprised at how beautiful and attractive she was, she was ten thousand times more beautiful than Kagome.

"Why is my sister-in-law so attractive?", Inuyasha asked himself.
