Sonoko and Shou have been friends since they were kids. Yet, one day, Shou surprised Sonoko by asking her out and attempting to kiss her. She refused his advances, believing that it was too early for that level of physical affection. She recalled watching a film with him that emphasized the significance of a kiss between two consenting parties. This belief encouraged her to delay any romantic notions.
Afterward, Sonoko returned to her classroom, where a boy confronted her and demanded that she yield to him. He attacked her and forcibly kissed her without her permission.
