The Patriarchal Alpha's Attachment Omega

It was miserable enough to be dumped by his lover on Christmas, but then Sungha is thrust into an Omegaverse world due to an accident. With parents who are dirt poor and a debt of 3 billion won hanging over his head, the only consolation is the existence of 'free love between the same sex.' It is then that Baek Leehyuk—a man with a foul disposition, but an undeniable beauty—suddenly approaches Seong-ha. “I’m in urgent need of a dominant Omega right now.” It is the most absurd and tactless proposal in the world, and it leaves a sour taste in his mouth, but... “So, you'll have to marry me.” Slowly, he finds himself drawn to this insolent third-generation chaebol.
