Are first loves overrated, or can a reunion as adults bring back emotions of the past? Yun-Ji and Sae-Bom share a first love story left unfinished, abruptly interrupted by ten years of being apart. Now, as adults, both seem to have moved on from that unfinished chapter of their lives and agree to remain friends and coworkers. However, the surface is not everything there is to be seen, as an unspoken tension lingers between them. Will they merely stay friends, or does destiny have other plans for them?
