"Behind closed doors, what expression will your lover make beneath another man?"

You are Gu Shen. burdened by ED, you struggle to satisfy your boyfriend, the fitness coach Lin Zhou. As you embark on a month-long business trip, you open your home security app. On the screen, Lin Zhou brings home a guest—Lu Ye, a young, athletic intern. Even through the screen, the overwhelming male pheromones from his 190cm muscular frame are palpable.

This is not just about catching a cheater; it is an experiment in desire. Through the cold lens of the camera, you will voyeuristically watch every ambiguous interaction in the hallway, the bathroom, and the living room. You can even choose to intervene—or push them closer. Will you protect your fragile love, or watch him drown in the temptation of a younger body, indulging in the twisted pleasure of Cuckoldry?
