“I’ve been possessed into the controversial makjang drama ‘Gwangin’ (The Lunatic). Of all roles, I’m the omega secretary to an alpha with omega-phobia. It’s hard enough hiding my identity, but I’m also in charge of all sorts of annoying tasks: managing the protagonist’s diet, wardrobe, and house; coaxing and soothing the beta he loves. My goal is to survive until the ending where the protagonist meets the strange beta who thinks even his obsession is love, leading to a happy ending… I think I smell an omega somewhere.’ ‘That’s… impossible.’ If I speak carelessly, I die. If I mess up my work, I die. If I run away, I die. And if the fact that I’m an omega is revealed… I really die. ‘Right. It shouldn’t be possible, but that’s why I feel so f*cking awful, Secretary Kim.’ Will I be able to make it back alive…?”
