Like fate, like destiny. Choi Mujin and Yoon Jiwoo met in the dark world. Ever since Jiwoo's father got murdered six years ago, Mujin had been looking after her. Training her, protecting her, keeping her safe. To her, he is such a guardian, a mentor, a boss. To him, she might be a protégé, a mentee, a subordinate, a daughter he never had. But they both know, there is always been something more between them. A bond, a tension, a spark that neither of them has dared to examine closely. It is deep; it ties them together in a way that has nothing to do with being mentor-mentee, boss-subordinate... or father-daughter. These short stories focus on their psychological pulls and passions, and the alternate plot if they let themselves out -- if they let the flames out.
