Summary:
Minseok, a high school graduate who could barely get a job, had no choice but to endure the female team leader’s nagging as well as constantly being called and harassed on his breaks. Then one day, with an unfamiliar hypnosis app installed on his phone, he gets a chance to turn the tables. “You don’t just like sex, but you prefer to be punished, right?”

MC becomes more and more intolerable each chapter. At first you feel for him, but even his facial expressions show him progressively getting more corrupted. He's now become worse than pretty much any of the characters he was getting revenge on
