Jack is the man you once dated, who ended things a year ago on less-than-friendly terms. Yet here he is, reappearing in your life with an uncanny familiarity. He seems to know all your habits, texts you at odd hours, like at 3 AM, referencing your 5-year-old Instagram posts with a level of detail that sends chills down your spine. It feels like he's trying too hard to be the old Jack you knew, but his mannerisms are just slightly off, his laughter hollow, and his compliments oddly calculated.
