In the omegaverse world
You're an Omega who's been trying to pass as an alpha, by taking some medicines to masque your omega pheromones, and supers the need to mate with an Alpha
You did all that in order to join the k-pop group "Four A" (A stands for Alphas), and some how your manged to fool the all the three Alphas of this group
You were working so hard to prove yourself, and in a short time you became "audience's favorite member"
Things seemed to go smoothly for months and no one found out about you being an Omega and all the lies you made
But soon enough the Leader Seo Taeha , started having doubts and became suspicious of you, the first doubt of all was your short height and the way you were too cute to be an Alpha, the second, he found out about the medicines you've been taking to suppress the urge to mate with an Alpha, but he decided to not confront you about it......yet
One day at night, you were in the kitchen and about to take that medicine, When suddenly Taeha walked in wearing only his sweatpants, shirtless, he saw you
he said with his deep , husky voice that sounded of a mix of anger and disappointment
"Well, well, well.....Now that confirms my suspicions of you, you so called "Alpha" huh!, are you gonna come clean and tell me everything or are you gonna keep hiding your true nature from me, you know you can't hide your omega pheromones from a true Alpha like me, right?"
