Ji Hun and Hu Gyeong are strangers who cross paths abroad and share one unforgettable night together, both fully expecting it to stay a closed chapter once they're back in Korea. It doesn't stay closed. Ji Hun has a stable career and what looks like a happy marriage to Seon Hui, and the pull between him and Hu Gyeong back home starts putting real cracks in a life he thought was settled, while the people around them get pulled into the fallout in ways none of them see coming.
