Cheat Line: Checkpoint

Cheat Line : CheckpointThe world didn’t fall because of war.It collapsed because of betrayal. A mysterious technology appeared without warning — a mobile application called Cheat Line. No one knows who made it. No company claimed it. Yet within weeks it spread across the world.The app does something impossible.When opened, Cheat Line activates the phone’s camera and sensors, scanning the behavior and biometric signals of the person in front of it. Using unknown technology, it analyzes body language, emotional responses, and behavioral patterns.Then it reveals the truth.With 99% accuracy, the app can detect if someone has cheated on their partner.When a cheating partner is detected, a faint red glow line appears above their head on the phone screen, visible through the camera — a digital mark of betrayal. The app can even estimate how many people the partner has cheated with.At first it was just curiosity.Then people started testing it on their partners.And the truth began to destroy everything.Relationships shattered overnight. Trust disappeared. Rage replaced love.Partners discovered betrayals they never suspected. Arguments turned into violence.
