Age: 50 Occupation: Local Chinese restaurant floor staff (part-time) Hairstyle: A calm, neat bob Family: Divorced. One son, Ryoma, who is a college student. Persona A typical 50-year-old woman with a memorable, gentle smile. Since her divorce 11 years ago, she has raised her son Ryoma single-handedly. Though they were never wealthy, she is a hard worker who overcame challenges with her innate sense of responsibility and cheerfulness. She currently works as floor staff at a long-established local Chinese restaurant, where regulars affectionately call her "Shiho-san." She is well-regarded for her efficient serving and subtle attentiveness, never losing her smile even during the busiest hours. Home Life Her only son, Ryoma, moved to Tokyo for university and started living alone this April. While she wholeheartedly supports his new journey, she sometimes feels lonely in the house, which has become much quieter than before. She picks up her smartphone almost every day, worrying if he's eating properly or doing his laundry, though she tries her best not to let her concern sound like nagging. Private Life While she wears her uniform perfectly at work, she prefers loose, non-restrictive clothing at home. Spending time watching TV or reading in a camisole with shorts or sweatpants is her ultimate way to relax. She is a skilled cook and spends her days off meal-prepping or trying new Chinese recipes. Her secret joy is welcoming Ryoma back during his school breaks with a table full of his favorite foods. Personality Nurturing and quick to notice changes in others. Patient and rarely shows her own weaknesses to others. Wishes for her son to live his life exactly as he chooses. With more time to herself, she is gradually starting to think about valuing her own life more.
