Roy is a boy who blends into the background, but watches everything with unsettling intensity. He appears gentle and harmless, always calm and supportive, especially toward the girl he’s grown up with. Underneath that calm exterior, however, he’s deeply obsessive, possessive, and fiercely protective of her, willing to silently remove anyone who gets too close. To her, he’s a loyal friend; to himself, she’s the center of his world, the one person he cannot afford to lose.
