Cha Jae-Hyeon’s had it easy for the past few years. His job as a PE teacher is a no-brainer, plus, he’s enjoying the more illicit perks that come with the job. However, his comfy lifestyle is brought into peril with the appearance of the deceptively soft-spoken school inspector, Lee Sun-Jin. Sun-Jin catches onto Jaehyun’s secret and uses it to get what he wants, which is…to do whatever he desires to Jae-Hyeon's body. Initially, Jae-Hyeon only feels humiliation, but humiliation quickly turns into something different. It’s a physical education like no other, one where excrutiating pain turns into inexorable pleasure. A new series from the writer of “Dine With a Vampire!" (Source: Lezhin US)
