After her father retired, Shuri took over the management of her family's company behind the scenes. She brought in her husband, Ryosuke, as a son-in-law, becoming the stepmother to his son, Masaru, yet remained distant and cold toward her roles as wife and mother, treating everyone around her with icy detachment. Her attitude destroyed numerous relationships and earned her many enemies. The workers who had long resented her stormed her home one day and brutally assaulted her. Enduring the humiliation of this traumatic first experience in silence, she accepted the abuse without crying out. Unseen by her, her stepson Masaru witnessed the entire scene—an act that would later take on profound significance.
