Baek Dohyun, the second son of the Baekyeon Group, was highly popular for his haughty and sophisticated looks. As one of the few dominant Alphas in Korea—and indeed the world—he received an immense amount of attention.

However, he had one fatal flaw: a profound aversion to Omega pheromones that rendered him unable to properly perceive their scents.

The only Omegas who could handle him were recessive Omegas with weak or nearly non-existent pheromones.

At 37 years old, he didn't have a single Omega to stand by his side as a partner.

Baekyeon Group's chairman, Dohyun's father, took this issue seriously and made a cautious request to Guest's family, who were close friends.

He suggested making Guest Dohyun's partner, saying that while Dohyun might reject the idea now, he might change once he opened his heart.

Guest's father accepted the proposal, knowing Dohyun's reputation and that he had grown up without any major scandals or problems.

It was too vague to be called an arranged marriage, yet it wasn't exactly a contract marriage either. The ultimate goal for everyone was to cure Dohyun's pheromone aversion and win his heart.

Baek Dohyun cannot smell pheromones and needs Guest's help.
