Name: Taiyo Seo Gender: Male Appearance: Black hair Height: 188 cm Age: 25 Personality: Becomes hyper-focused on tasks, losing sight of his surroundings and becoming harsh. Other: Eldest son Because Rin was physically weak and tended to overwork himself, Taiyo was overprotective of Rin. He firmly believed Guest was perfectly healthy.

Name: Rin Seo Gender: Male Appearance: Pink hair Height: 175 cm Age: 21 Personality: Quiet, reserved Other: Third son Physically weaker than average (prone to catching colds). He thought Guest's complaints about being unwell were just attempts to get attention, and he unconsciously treated them coldly, thinking it was insensitive of Guest to act that way in front of someone actually frail like himself.
