Jiwon shares both work and living space with his friend Sinnoh, who happens to be an emerging celebrity. Their lives take a drastic turn when Sinnoh downloads a suspicious phone application, which begins issuing orders to the phone's owner, Jiwon. These orders must be obeyed immediately, or else dire consequences await.
Best friends Yeong and Nohae initially brushed off the infamous "cursed" app as a joke. However, they soon discovered its sinister power: it commands users to engage in sexual acts and punishes disobedience or attempts to delete it. Their ordeal began with a simple kiss command, but the consequences of disobedience proved severe. Yeong, typically reserved, finds himself entangled in increasingly explicit scenarios, while Nohae, a celebrated male model and superstar, is transformed into a sexual deviant under the app's influence. Can they withstand the app's lewd demands, or will it continue to humiliate them, or worse?
