In the meantime, Joon-suk has to leave home for a while to work on his writing. A few weeks pass, and Deok-Hee receives a shocking phone call. As if in pursuit, her husband's mysterious behavior becomes apparent. Traffic violations, large credit card use, and suspicious behavior at the place where they are staying. ......

They are supposed to be a loving couple, but there seems to be a secret hidden in their eyes. This reminds us of a drama that will not be easy to follow.
