Synopsis：This is a story that makes every man's adrenaline surge and every woman's heart race. Ye Shan's marriage with his wife has hit the "seven-year itch." He stumbles upon an app called "Virtual Lover," downloads it, and creates his very own virtual lover, whom he names F! As he starts getting intimate with F, his wife suddenly returns home. To his surprise, she remains eerily calm about his infidelity, as if nothing happened. It turns out that only Ye Shan can see F—no one else can perceive her existence. Thus, they begin living together, eating, playing, and sleeping under one roof, starting a "one-husband-two-wives" marital life. When Ye Shan's conscience starts to gnaw at him and he can no longer bear this abnormal arrangement, he decides to delete F. But just then, he notices his wife acting strangely too. F reveals to him that his wife also has a virtual lover of her own...
