Reversal (Saejo)

Living as a beta, Lee Hajin disguises his real identity and suppresses his recessive omega trait to please Jinseung, the son of the CEO. He carries the burden of a debt and leads a solitary life without the support of a family. During a meeting with a client at a designated location, he encounters his first love, Sunghyeop, who is now a CEO. Despite years of separation, their pheromones signal a powerful attraction, leading Sunghyeop to propose a sexual relationship restricted to only Hajin. Sunghyeop used to live and sleep at Hajin's house when he was a driver's son.
