Affair is not acceptable, but this drama break that phrase((anyway affair is sin :(...)).. sinful love is better than hopeless marriage..
Slowly you will merge and long for main lead love.. u will say hooray while they get alone and go for date. while having affair and going out will make them have guilt. U too will feel that guilt and feel sorry for them hving that guilt... Guilt pleasure concept may be.
Music and Melo top notch.. i didn't long for Second lead couples.. Main lead couples were beautiful like poem..
Eventhough it was taken from J drama i found Korean version was gorgeous...
Watch once and see wheather u fall for them r not??
