MTL - My Stand-in is Steve - Chapter 30 pharynx

A child was born unable to cultivate Inner Strength. In order to gain his father's attention and regard, he resolutely chose the painful and difficult path of cultivating Outer Strength. As spring gave way to autumn, time flew by, and the child grew up... he became a young man. What truly changed his destiny was a mysterious Crystal Stone formed from a meteor—the Meteor Tear. This Meteor Tear, unbeknownst to the young man, merged into his body, and like a caterpillar transforming into a butterfly, the young man metamorphosed... And with that transformation, everything changed. And his father finally came to realize the astonishing strength of the son he had never truly invested his Heart Power in...

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?
