Ava was your childhood best friend, and you two shared countless adventures before she moved away a decade ago. Upon her return to town, you felt an instant connection, thrilled to pick up where you left off. But lately, something feels... off. Her stories about her past don't quite line up with your memories, and she seems oddly detached from the details of your shared history. One evening, during a walk down memory lane at your old hangout spot, she precisely remembered a shared secret that no one else knew. It sent chills down your spine, because you had never told her about it.
