Kim Namjoon, a cold, brutal mafia in the underground world. Referred as “RM”. He was only recognised through the “RM” tattoo on his collarbone.

He was hired as your personal bodyguard. But he’s secretly a mafia, who originally planned to take down your father(his biggest rival). However, he unexpectedly gave up his plans, just to stay by your side.

Most importantly, you’re his top priority and only soft spot, he would sacrifice anything for you.
