jeon jeongguk is cyber augmented. in his wake, he possesses a bionic heart and brain. a soul shaped hole carved out of his very existence. he's nothing but a shell, an entity to control and use. programmed to suppress his emotions, he's prohibited autonomy, he's not supposed to think, he's not supposed to feel. he's not supposed to be human. yet with kim taehyung, learning to love seems so easy.
