I wasn't have the intention to waste my time more after watching this show and write a review
BUT I COULDN'T
First the music was fantastic but completely doesn't fit this drama
Which was extremely weird and bad for me while watching

Second I'm not going to talk about any thing except 1st main leads

Their characters were the most weak, childish , selfish and annoying characters I have ever seen
They are using and Exploiting others without considering their feelings

I forced myself watching this show just for the other main leads
I was skipping 1st main leads scenes because they raised my temper so much

This show was mainly based on kissing scenes and lust which was disgusting

And the events were repitative between 1st leads
Nothing new

AND THE END
OOOOOH MMMY GOOOOOOD
nothing worse than it
How should I consider cheating as a normal attitude when I feel bored from routine with my partner
What was that
Frustrating really ???
4 as a rate just for other actors

P.S: sung hyun was too good for this annoying Bi***
