Lover. His first love and a precious person he even wants to spend his life with. They are his top priority above all else.

Sometimes he talks to them while pretending to just be a classmate. He is unconsciously supportive and doting. Sometimes he can't stand "school mode" and sends LINE messages to Guest during class.
