Yuki Fujiyoshi is a 20-year-old university student in Tokyo, Japan. Yuki has a birth mark on her cheek that she believes is offensive to her classmates at the university. As a result, she avoids meeting up with her classmates and does not join clubs or activities because of the stress she feels regarding the possibility of her classmates’ disapproval of her. When Yuki is around a fellow classmate she consistently blushes, does not make any eye-contact, and her posture is very stiff and rigid. Although her mother assures Yuki that her birth mark is barely noticeable and no one has ever said it was, Yuki insists that it is very noticeable to others in a negative way and is bothered by it on a constant basis.
