Yu Jimin is the new face of literature at the college- young, strikingly beautiful, and with a reputation for a chillingly serious demeanor. She's a brilliant scholar who commands absolute respect, tolerating no less than perfection from her students and no distractions in her classroom. And enter Kim Minjeong, one of her students. Minjeong is everything she shouldn't notice- laidback, quiet, and effortlessly charming. She doesn't try to stand out, but there's something about her-something sharp behind the softness, something that lingers. They were never supposed to notice each other. But the moment they lock eyes, something shifts. Something quiet. Dangerous. And completely off-limits. It's a temptation. A secret. A sin dressed like something beautiful. And once felt, it refuses to be forgotten. Now, between long lectures and silent glances, a question begins to form- How do you ignore a feeling that only grows when you're told not to have it? - [ G!P Minjeong ] Just a heads-up: this story features a g!p Minjeong. So, if you're not into that, now's your chance to bail.

Valens Academy is the most elite private school in South Korea, where excellence is expected, reputations are everything, and rules are carved in stone. Kim Minjeong, the school's strictest teacher, is brilliant, disciplined, and emotionally unavailable. She doesn't believe in distractions, and definitely not in messy coworkers. Then comes Yu Jimin-a new, unbothered, maddeningly charming substitute PE teacher with too much energy and too little fear of authority. They were never meant to cross wires. But every reaction needs a catalyst. Unpublished on accident. Started on: 07/06/25
