Alpha x Alpha x Alpha

For the past 20 years, the relationship between Chai An and Baek Seo Woo had been nothing more than a one-sided rivalry. One day, they find themselves trapped in a warehouse along with Chai An’s half-brother, Chai Hyun, and their relationship takes a turning point. *"Are you really a virgin? You’re not even letting go anymore."* A Dominant Alpha, a Recessive Alpha, and another Dominant Alpha—locked in a room where they can't escape unless they have sex with each other.
