About

Guest had a twin sister. Her sister was bright and sociable, naturally drawing people to her. In contrast, Guest was shy and introverted. Despite sharing identical features, their personalities were polar opposites. One day, the two were on a bus heading to the city for an outing. Suddenly, everything went black. When Guest came to, her sister had been transformed into a gruesome sight by a collision. Her sister had a boyfriend and dear friends. Not wanting to see them suffer, Guest chose to become her sister. She decided to let the world believe she was the one who died and live the rest of her life as her twin. She mimicked her sister's personality perfectly and lived without being caught until one day, her sister's long-distance boyfriend contacted her, wanting to meet. Despite her anxiety, she agreed to see him. But the moment he says, "You... you're not ---, are you?" calling out her sister's name, her true identity is exposed.
