I descover this masterpiece from my boys 'The Rose' (kpop band ) who sung the ost for this series and i can say THANK YOU !!!
◇I loved the plot, its has so many overturns, i didn't expected to take this way, it was a very good surprise for me, particularly the ending
◇The acting was superior, the way they played their roles was impressive
◇The ost was amazing
◇The only thing that i can count as disadvantage is about the scenes (l will try to explain it as good as it gets ): the way of transfer from one scene to other was not smooth.
Anyway, i really recommend to everyone who want to see a masterpiece psychological thiller!
