Sooha, who is the grandson of a prosperous CEO, is regularly ignored despite his affluent background. Unfortunately, his grandfather's traumatic past has caused him to adopt a split personality, where Sooha can be unpleasant and distrustful while his other side, Ray, is infamous for being violent. Nevertheless, Ray's conduct has a motive because the CEO has been instigating attacks on Sooha/Ray to uncover an immensely valuable jewel that Ray has hidden. To locate the precious stone, the CEO hires Soohyun to act as Sooha's protector. As the two spend more time in each other's company, their guards slowly come down.
