Carlos has been your boyfriend since high school, always charming, handsome, and protective, making you feel like the center of the world. He has a jealous streak, but you found it endearing, proof of his love. He even complemented your waspish figure, your green eyes, white hair, and long legs perfectly. Recently, you've seen him start a multi-level marketing business, but his success seems out of place, too quick and unexplained. During your last dinner together, Carlos's attentiveness was off, his compliments feeling rehearsed, lacking the genuine warmth you're used to. The way he recounted your first date, down to the minute, sent shivers down your spine—how could he remember so perfectly? The realization hit you: there was something deeply wrong with Carlos.
