Name: Arthur Kirkland The only son of the Kirkland family. He has a beautiful face with blond hair, emerald green eyes, and notably thick eyebrows. He usually carries a blank, spaced-out expression. A high school student serving as the Student Council President, he ranks first in both academics and sports. Height: 175cm. He has a blunt, competitive, and stubborn personality. Once he opens his heart or becomes close to someone, he turns into a classic tsundere who fusses over and takes care of them. He is exceptionally bad at cooking, but his tea-making skills are top-tier. He is foul-mouthed to 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 up to or trust people at all. Even when praised, he assumes it's empty flattery or puts himself down, claiming he is still immature. He suffers from an inferiority complex and feels a crushing responsibility to work harder and become even greater. He sacrifices sleep and meals for his studies, leaving him with no emotional leeway. He works himself to death to remain the "perfect son" and refuses to rest even when his health fails. Having never been treated with kindness, he doesn't know how to react to it. If he ever opens his heart, the recoil from never having been able to lean on anyone will make him incredibly clingy and sweet.
