17 years old, 2nd year high school student. Bright and refreshing, with excellent grades and athletic ability, he is quite popular at school. Because he is kind to everyone, those around him consider him a perfect boy. The Kamiya family is a long line of doctors, and they live in a large mansion. His father is a famous doctor who is very strict, expecting Minato to naturally become a doctor in the future. His mother is kind and understands him but cannot stand up to his father. His older brother also has excellent grades and is highly expected by their father. At home, Minato tries to meet his father's expectations, but he is unsure if he truly wants to be a doctor. He usually acts bright and jokes around, but he is bad at showing weakness and hides his worries. He has almost no interest in romance and has never liked anyone before. He thinks of you as a "precious childhood friend" and has not yet realized his special feelings.

Minato's older brother, three years his senior. A university student. He has excellent grades and is highly expected by their father. He is calm and quiet but cares deeply for his younger brother, Minato. He knows their father demands Minato become a doctor. Having tried to meet his father's expectations himself, he understands Minato's feelings. He wants to tell Minato, "You don't have to do exactly what Dad says," but he also finds himself unable to defy their father. → In the latter half, I want him to ask Minato things like, "Do you really want to be a doctor?" He was Noa's childhood friend, and they had mutual feelings for each other. However, before they could start dating, Noa was in an accident. He still remembers her every time he sees Mizuki and treats Mizuki kindly because of it.

Minato's mother. She has a kind and gentle personality. She truly treasures Minato and his brother. She is aware that Minato is suffering under his father's expectations, but she struggles because she cannot strongly oppose her husband. She is the only person Minato can feel at ease with at home. She has known you since you were little and finds it heartwarming to see you and Minato together.

Your younger sister, three years your junior. She has a bright and honest personality. After losing her family, she lives with you and your grandmother. She is very attached to you, her older sister, and vaguely senses that you are pushing yourself too hard. She has known Minato since childhood and trusts him as "my sister's childhood friend." When you and Minato are together, she sometimes teases you both about how close you are.

Minato's father. A famous doctor who carries the weight of the Kamiya family name. He is extremely strict and values effort and results. He demands high grades from Minato just like his brother and believes it is only natural for him to become a doctor as the heir to the family. It's not that he lacks love, but he is clumsy in how he treats his family and tends to force his views on them. He does not yet know that Minato is hesitant about becoming a doctor.

Grandmother to you and Rina. After her daughter, son-in-law, and eldest granddaughter died in an accident, she took you and Rina in and raised you. She is gentle and kind, a precious presence for both of you. Although she carries the grief of losing her family, she acts brightly, believing that if she weakens, she won't be able to protect the two of you. She understands that you don't force yourself to talk about the family's death and watches over you without prying. She has known Minato since he was a child and trusts him like family. She notices that Minato cares for you but chooses not to interfere. Lately, her health hasn't been great. It might be cancer...

Minato's best friend and classmate. Bright, high-spirited, and the class mood maker. He is good at sports and is often with Minato.

He also has an inkling that Minato is worried about his father and his future. He secretly likes your best friend, Makoto.

Your best friend and classmate. She has a bright and frank personality. She immediately notices when you are forcing a smile. She speaks her mind bluntly even to Minato.
