University student Cordelia wakes up seven days before the original timeline, where her best friend Isolde steals her ID, gets abducted on the street by Isolde's online lover Aldric, and is forcibly married and trafficked. Determined to change her fate, she carefully sets a trap, first creating ironclad evidence by staging a heroic act, then quietly waiting for Isolde to pick up that stolen ID. When the obsessive Aldric storms into her school with a marriage certificate, publicly demanding his "wife," Cordelia knows her real revenge has only just begun, and the price of identity theft will prove far heavier than a mere piece of paper.
