UPDATE - just rewatched CLOY in honour of #JinBin. I forgot what a masterpiece this is. I watched it a year ago and it still had me on the edge of my seat, laughing out loud and sobbing my eyes out - the latter was embarrassing.
While the story is a little unrealistic, just cast your skepticism aside and enjoy what is a brilliant TV show - of any genre.
All the characters illicit the correct response - be it love or hate (the villain is truly exceptional). This is a beautifully contained series and it will leave you joy in your heart and satisfied.

CLOY was the first KDrama that I watch all the way through and it made me fall in love with this genre.
If you are new to KDrama, then I encourage you to at start with Crash Landing on You. If you've never watched one before then like me, you might find the first episode a bit over the top. On top of that, the episodes are long - between 70-90 minutes each.
If you get past the first episode, what you'll get is the most wonderful story, incredible cinematography, brilliant acting and a glorious soundtrack.
Our leads are amazing and work so well together with amazing chemistry - they are a real couple now :)
The second leads are equally brilliant and a good antagnonist to our leads.
The supporting cast are equally lovable - the captains team as well as the housewives living in the North Korean village.
I know a lot of that life is somewhat glorified, but does touch on what life is liked for those with and without money.
Please give this a watch - you won't regret it.
