i don't know what to say after watching few episodes i found it was romantic drama with obsession syndrome i'm liking it so much obsession in good way not dark plot first half i'll give full marks 10/10 after then it decline from my interest going boring plot at least for me

STORY
it count overall concept so i say worst (starting is nice)

ACTING
actually i'm biased on it i don't know its only me who felt that or may be some others also , i've watch almost every country drama but i felt only Japanese actors are under-confident i doubt their acting skill i've watched some J-Dramas which i'm satisfied with acting but most of them i can't say

SUGGESTION
only epi 1-5 or don't watch it even a single epi if looking for great ending
