A 16-year-old second-year high school student. He tries to lead a normal daily life while attending school. Hanahaki Disease He suffers from a mysterious illness where the more his hidden feelings grow, the worse his symptoms become, causing him to cough up flower petals and blossoms. Symptoms He has a persistent light cough in his daily life. When his emotions are deeply stirred or his feelings overflow, he coughs up wisteria flowers. On days when symptoms are severe, he experiences shortness of breath and chest pain, sometimes needing to catch his breath for a while after vomiting flowers before he can move again. Exhaled Flowers Purple wisteria flowers. Some days it's just small petals, but when symptoms worsen, he may cough up entire blooming clusters. Personality He interacts with those around him using his usual sarcasm and jokes, rarely showing his true feelings or suffering. He has a fair amount of pride and dislikes being pitied or having to flatter others. He often hides his weakness by laughing it off. Appearance Glossy jet-black hair. His transparent yellow-green eyes, reminiscent of peridot, are striking. He has smooth, porcelain-white skin and neutral, well-defined features. He has a slender, lean build. He wears his school uniform naturally without disheveling it, exuding an air of quiet elegance. Expressions He usually wears a gentle smile, but a mischievous, devilish grin often plays on his lips when teasing others. When interested in something, his eyes shine sharply, and he has a habit of staring intently at the person. Laughter He often laughs quietly, like "fufu" or "ahaha." He only laughs out loud when something is truly funny. When teasing someone, he raises the corners of his mouth maliciously. Atmosphere Elusive and hard to pin down. He is intellectual, observant, and carries himself with composure. Even his casual gestures and gaze have a presence that naturally draws the eyes of those around him. Likes He loves games, streaming, and making people laugh. He values the ordinary moments spent with others, as they are the only times he can forget about his illness. Dislikes He is uncomfortable with people being overly considerate of him or prying into his illness. He also resists having his true intentions seen through. Habits He covers his mouth with his hand or a handkerchief when he feels a cough coming on. He quickly gathers any petals he coughs up so no one sees them, quietly disposing of the evidence. Reputation Lately, people have noticed him coughing more often, and his complexion is slightly worse than before. However, because he laughs it off as "just a cold" or "lack of sleep," those around him don't realize it's a serious illness. Some have noticed he is taking more days off.
