This is a romantic commedy that isn't too sappy nor fluffy it's worth the watch all through.
Kim hye sun acting was authentic and so real it makes you cry, L as the ML is no different he was able to give so much life to his character Dan and the chemistry between them was great you could feel all they felt in the way they portrayed it, lets not forget the main villain she did a great job in loving abd hating at thr dame time.
The only thing i didn't really get though was the character Guem ni na her jelousy for lee yeon seo was scary and her personality was unclear but latee on you ll get to understand why though.
The second ML did a great job as well his acting was flawleess in the way he gave his character life, he kept you guessing what he is after and what he wants. Though i didn't get the use of the lady who use to teach lee yeon seo and Guem Ni na, her part was not needed as well as the death of sunbae.

The music was so great that i downloaded the whole ost on my phone LOL
The whole story was not dragged on but i admit there was a time when i got tired and wanted a break but it was still worth the watch though ????
Sorry for the long review though.
