Joong Han first visits Hyo Jung, Guk Hwa’s former roommate who has recently moved out not long before the incident, and demands answers to her questionable behaviour. This then leads Joong Han to people closely related to Guk Hwa one after another. Meanwhile, Hyun Soo goes through a crime scene re-enactment, but he collapses shortly after.
