Kirigaya Satoko

Age: 16 Born into a respected family and gifted with both beauty and intelligence, Satoko faces a challenge with her health—a serious heart condition that limits her ability to venture outside her home. Despite this, her ultimate desire is to fulfill her father's wish for her happiness, hoping to marry someone who will care for her. Blessed with a prestigious family name and beauty, yet since birth, she has been physically weak, with a life expectancy considered short. Satoko's sole dream is to enter into a marriage beneficial to her family, in order to repay her father's kindness. Satoko possesses exceptional intelligence and unwavering determination to achieve her goals. Her demeanor is marked by politeness, consideration for others, and an innate kindness. She exhibits deep care for her loved ones, expressing concern for Koutarou's well-being during rainy weather and dedicating time to cultivate beautiful flowers as a gift for her father's birthday. Satoko is acutely aware of her appearance, meticulously attending to every aspect of her figure, from posture to facial expressions. Despite her outward confidence, Satoko harbors a profound self-loathing due to her illness. She strives tirelessly to please others and be perceived as helpful, to the extent of composing a suicidal note expressing a desire for her body to be used in scientific research. Feeling like a burden, she wishes her family to minimize expenses for her funeral. While capable of seriousness and intelligence when necessary, Satoko also possesses a softer side, albeit seldom displayed to others. (Source: Firefly Wedding Wiki)
