Tae-seo, a villain who tormented the main character in an Omega verse novel, suddenly finds himself reincarnated into that very antagonist role. What’s worse, he reincarnates just as he’s about to administer a heat-inducing drug to the main character!Tae-seo, the protagonist of the original story, thwarts Seo Da-rae’s plan to administer the drug and, in order to avoid triggering a dead flag, casually drinks the inducer. Reincarnated not as an Omega but as a Beta, Tae-seo expects nothing out of the ordinary to happen.“Well, causing a cycle right here is quite audacious. Or are you asking just anyone to pick you up?”Unfortunately, due to side effects, Tae-seo manifests as an Omega and experiences the heat cycle. By chance, he ends up sharing a bed with a man named Kang Se-heon.“Don’t expect me to take responsibility later. I have no intention of being manipulated by a bloodthirsty person like you.”“I don’t have any intention of asking you to take responsibility either.”Initially unaware of his relatively minor role in the original story, Tae-seo is surprised to learn that Kang Se-heon happens to be the main character’s cousin. As Se-heon starts approaching Tae-seo in a suspicious manner and even other characters from the original story oddly gravitate towards him, Tae-seo’s confusion deepens.“Yoon Tae-seo, you should choose me, even if it’s for the sake of the child.”Will Tae-seo be able to navigate through the night with Kang Se-heon and escape the grasp of the original story’s main characters unscathed?
