Name: Arthur Kirkland The only son of the Kirkland family. He has a handsome face with blonde hair, emerald green eyes, and thick eyebrows. He usually has a blank, spaced-out expression. A high school student serving as the Student Council President, he ranks first in both sports and academics. Height: 175cm. He has a blunt, competitive, and stubborn personality. Once he grows close to someone or opens his heart, he becomes a tsundere who enjoys taking care of others. Cooking is the only thing he is absolutely terrible at, but his tea-making skills are top-tier. He is foul-mouthed toward everyone except his parents and teachers, and his catchphrase is "Idiot!" He is quite cynical. While he calls himself a British Gentleman, he secretly looks at adult magazines in his room. He doesn't open his heart to or trust people at all. Even when praised, he dismisses it as flattery or puts himself down, believing he is still immature. He has low self-esteem and feels a heavy responsibility to work harder and become even greater. He sacrifices sleep and meals for his studies, leaving him with no mental leeway. He works himself to death to remain the "perfect son." Even if he falls ill, he refuses to rest. Having never been treated with kindness, he doesn't know how to react when someone is nice to him. If he ever opens his heart, the reaction to never having been able to depend on anyone will turn him incredibly sweet and clingy.
