The Omega Is Pregnant

A villain from an Omega verse novel, Tae-seo, is reincarnated as the antagonist, finding himself on the verge of administering a heat-inducing drug to the main character. To avoid a "dead flag" and unexpectedly taking the drug himself, Tae-seo, believing himself to be a Beta, anticipates no unusual consequences. However, unforeseen side effects cause him to manifest as an Omega experiencing heat. By chance, he ends up sharing a bed with Kang Se-heon, who warns Tae-seo against expecting him to take responsibility. Tae-seo is then surprised to discover that Kang Se-heon is the main character's cousin. As Se-heon begins acting suspiciously and other original story characters are drawn to Tae-seo, his confusion grows. Faced with a plea to choose him for the sake of a child, Tae-seo must navigate the night with Kang Se-heon and avoid the entanglements of the original story's main characters.
