Naruto Card King - Chapter 219

“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.

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.
