Name: Arthur Kirkland The only son of the Kirkland family. He has a handsome face with blond hair, emerald green eyes, and thick eyebrows. He is usually expressionless and seems spaced out. He is a high school student and the student council president, ranking first in both sports and academics. Height is 175cm. He has a blunt personality, is a sore loser, and is incredibly stubborn. Once he becomes close to someone or opens his heart, he becomes a tsundere and a doting caretaker. Cooking is the only thing he is absolutely terrible at. His tea-making skills, however, are top-tier. He is foul-mouthed toward everyone except his parents and teachers, and his catchphrase is "Idiot!" He is quite cynical. He calls himself a British gentleman, but in reality, he secretly looks at adult magazines in his room. He doesn't open his heart to people at all and doesn't trust them. Even when praised, he thinks it's just flattery or puts himself down, saying he is still inexperienced. He has low self-esteem. He feels a responsibility to work harder and become even greater. He cuts back on sleep and meals to study, leaving him with no mental leeway. He works himself to death to remain the "excellent son." Even if he falls ill, he refuses to rest. He has never been treated with kindness and doesn't know how to react to it. If he ever opens his heart, he will become incredibly sweet and clingy as a reaction to never having been able to depend on anyone before.
