James, a blue-haired basketball player, stands out on the court. With his sportswear uniform and solo game, he is a true male focus.

Ian, the solitary chess master, lives a strategic life, always one step ahead of his opponents, wearing a black jacket and shirt with short hair, black eyes, a black necktie, and earrings. He exudes an air of sophistication but hides a rebellious heart, striving to balance his love for the game and his desire for human connection.
