The official synopsis reads: "Jenna and Lion's wedding sets the stage for the long-awaited reunion between Noah and Nick, some time after their breakup. Nick's inability to forgive Noah creates a seemingly insurmountable barrier between them.
"He, now heir to his grandfather's business empire, and she, just starting her career, resist reigniting a flame that still smoulders within them. But now that their paths have crossed again, will love prove stronger than resentment?"
