This drama would have done better if it was shorter. The writers had a brilliant cast to work with that gelled really well together. They had such interesting material for the 2nd love story between Pyung Hwa and Rowoon. I loved the sisters character because she wasn't devilishly evil, she wasn't trying to kill her brother or anything insane. So much potential was wasted. The writers/directors/producers were so obsessed with the visuals they forgot to bring any substance.

Lack of character development - For any of the side characters I would have loved to have seen some development.

What happened to Hwa Ran's mother? Why did they make it seem like she wasn't her father's daughter? Does she love her husband? How did they meet?

Pyung Hwa had the most interesting background and as a throw away we learn the pilot was her ex? Why did he register the marriage? How did she confront him then? I would have loved more of Rowoon's background, how did he become to be such a great person?

Da Eul's ending was wasted too. Get her together with someone better. Being single is better than that loser of a husband. He didn't learn anything at all.

Unclear ambitions for the main leads. Won wants to own everything but settles for the hotel? Why doesn't she open a hotel with her name Sa-Rang that means love in Korean, rather than Amore? WHY? Won is busy building an empire, why can't she do it at his side? The resort hotel could have been the starting place? She worked hard to get to the top of her field and what? She starts over? She earned a position at King Hotels. She would have earned that promotion!

It was just too long for no reason. But the parts I didn't fast forward through were nice.
