After dying on his first day as a teacher while saving a student, Cha-heon wakes up possessed as an extra in a high-teen romance webtoon. His only goal is to return the body to its rightful young owner and move on to the afterlife. However, complications arise: he is trapped in the body of Shin Cha-heon, a Beta who emits intense Omega pheromones, attracting unwanted attention from men—specifically, minors. Caught in an Omegaverse setting that makes no sense, Cha-heon finds himself constantly harassed by aggressive confessions from high school boys. Between the relentless flirting, constant boundary-crossing, and the stress of dealing with 'puppy-like' younger men who offer him everything from their entire net worth to their devotion, Cha-heon is desperate to escape his new reality before he crosses a line he can never come back from.
