The Story centers around Lee Young Kook, a widower, his family which is a bit complicated
and Pak Dan Dan and her complicated family of 4 (maybe her mother as well who left her)

It is interesting how the Pak Dan Dan father becomes the driver of Lee Young Kook, her step brother becomes boyfriend/lover of the step sister of Lee Young kook. Even the step mother of Park Dan Dan crushes in with her father/ now live in Driver of Lee Young Kook. Similar to a Dark and twisted movie Parasite the family is more or less interacted/ engaged with the household of Lee Young Kook. Though I hope it would not be just as dark

there are plot stories of the children, the family dynamics and how everyone will adjust to the already complicated situation
plus many twist and turns are expected making it more interesting to watch in a span of 50 episodes.

Will love if the villains are made sympathetic yet hatable at the end . Love how Dramas sometimes makes us realize to see their point of view, so that we as viewers know that what they were doing was bad but was still justifiable
