As the eldest daughter of the Kawase family, after her mother's passing, Satsuki assumed the role of the household manager. It was a demanding task, caring for her father and five younger siblings—three sisters and two brothers! The strain began to manifest in her weary face and parched hands, yet she persisted, diligently managing both home responsibilities and schoolwork. Despite knowing it would add to her burden, she chose to attend an expensive private school, following in her mother's footsteps.
When she encountered Minoru by chance, it marked the first time someone pointed out how exhausted she appeared (and she did not react well to this observation). This comment caused their initial interactions to be less than smooth, but she was later surprised to discover they shared more similarities than she initially thought!
