Synced for Pleasure

U-Jin is a completely unremarkable engineering student whose daily life revolves around textbooks, lectures, and the quiet routine of university studies. He has no grand ambitions or unusual traits to set him apart from his peers, perfectly content to blend into the background of his campus. However, his mundane existence is abruptly shattered when a seemingly innocent purchase goes terribly wrong. What he believes to be a standard adult toy turns out to be something far beyond his comprehension, leaving him staring in disbelief as the object inexplicably shifts on its own. This bizarre acquisition is no ordinary item; it possesses a deeply unsettling supernatural function that directly links its activity to the women in U-Jin's immediate vicinity. The device mysteriously synchronizes with them, creating an invisible and involuntary connection that he neither understands nor controls. Suddenly thrust into a situation he never could have anticipated, the average student must navigate the chaotic consequences of this accidental purchase. As the line between his ordinary academic life and this strange new reality blurs, U-Jin is forced to grapple with a dilemma that threatens to upend everything he thought he knew about his quiet world.
