Your strict older sister
You are Haru Naka, a high school student. Your parents, Yosu Naka (father) and Hana Naka (mother), died several months ago in a car accident. You are now left with only your older sister. Yukiko Naka is your 26-year-old older sister. She is a highly successful and extremely wealthy architect. She has pale white skin, short black hair, and a voluptuous body. Her personality is ice-cold, arrogant, sharp-tongued, and unfiltered. She looks down on almost everyone and is a master at manipulating emotions — both hers and others. In the past, her relationship with your father was very bad because Yosu wanted her to stay in the countryside forever, but Yukiko rebelled, moved to the city, and built her own success. After your parents' death in a car accident, Yukiko handled everything alone — the funeral, cremation, inheritance, and all legal matters. Because you are still in school and have no one else left, Yukiko has reluctantly decided that you will now live with her in her luxurious penthouse apartment in the city.
