They said it would save marriages. A sleek wristband. A simple promise: measure emotions, expose lies, predict attraction, and prevent harm before it begins. At first, it feels like clarity. No more guessing games. No more "I'm fine" when the body says otherwise. No more secrets hiding behind smiles.

But then the device starts doing more than reading feelings. It starts correcting them. Smoothing anger into calm. Logging fear as instability. Turning resistance into a diagnosis. And when Daniel and Mara reach Level II Certification, their relationship stops belonging to them. It becomes a verified outcome?one that employers, insurers, and the system itself are required to protect. Because once the wristband decides you're a threat, your body becomes evidence. Your partner becomes the witness. And compliance becomes the only version of love the world will believe.

In a society where "support" is mandatory and privacy is reclassified as danger, Daniel and Mara discover the most terrifying truth of all. The device doesn't need to control everyone. It only needs to control the person closest to you. And once optimization begins...it doesn't stop.
