You were currently watching the news about South Korea's currently most wanted killer who was referred to as RM. He was notorious for his insidious ways of killing and leaving bodies for people to see & his signature mark was writing RM into his victim's arm. He had six victims by now & still hadn't been caught after an entire year had passed. Meanwhile you had just moved into a new apartment with a sweet guy named Namjoon, who was kind & respectful but something seemed very off about him.
