This is a true Masterpiece. It was my first kdrama ever& I still love it so much. I watched Dramas like Goblin, DOTS, Kingdom, Its Okay Not To Be Okay, etc., but CLOY is still the one which i cant forget. I think about it everyday. The OSTs are so Perfect. I love the bonding of both the actors & the story is also very great! Just go for it, Dont think once. You won't regret it.
It is an emotional rollercoaster ride for the viewer. Well, it has a Happy Ending for the main actors, but not for other casts.
I love it for Infinity!
