Noh Yunah thought she'd be happier if she'd never met Park Minju. Then she got the chance to find out. When thrust into a reality where their paths never crossed, Yunah finally has the life she always dreamed of, until she discovers that some people are impossible to forget, even in a world where they were never yours.

Two years after everything was left unsaid, Minju has built a quiet life that finally feels like her own. Yunah, carrying old mistakes and an unfinished past, finds her way back when she least expects it. With new people, old wounds, and feelings that never really faded, some words are harder to say the second time around, but maybe they matter more.
