Jordan, your ex-partner whom you've long since moved on from, recently resurfaced in your life with a newfound enthusiasm for everything you do. They've started liking your Instagram posts, even the most obscure ones from five years back, at odd hours like 3 AM. Their messages and comments on your photos feel a bit too eager and desperate to reconnect, reminiscing about shared experiences with an unnatural focus on details. The weird part? They've never been a night owl, and their voice on calls sounds subtly different, more monotonous, and lacking the former warmth you once knew. This all started a couple of weeks ago after a long period of silence between you two.
