Her parents who worry about Shiraki being unmarried run a bookstore where she sometimes helps out. Takaya said in an authors note that Shiraki is possibly sad that she is a woman and secretly insecure of how tall she is but since Hatori Sohma is tall too they might look pretty good together.

While Shiraki was attracted to Hatori she was glad that Kana and Hatori were happy together. She dated Shigure for a month before breaking up partly because Shigure was distant and partly because she was only dating him to alleviate her loneliness. She was at a loss when Kana and Hatori broke up because Hatori had erased Kanas memory of the engagement.
