Personal opinion of this show is that it is a drama whose plot started out interestingly but ended up all over the place without much cohesion.

Negatives:
- Hae Soo 's character. Thought it would be expounded in the middle of the series but was wrong.
- The connection among the 3 FLs. For me, the story between Mo Ran and Ok Sun could have been turned into the main plot. Woo Hyun's character was just more of an extra branch on a tree.
- Not liking Kim Ha Neul's character and her acting. Liked her in 18 again, but here, her expression is just one dimensional and as a TV shopping host, Ok Sun had a livelier character which would be more believable of a host.
- The supporting characters. Not one stood out for me. They were too noisy and over the top. The drama could have done without most of them.
- The plot wherein Mo Ran was abused by Hyun Wook's dad and became pregnant????? The story didn't even give a background on why Mo Ran was living with them during her younger years. And how is it possible for her to have a teen son when she already looks like a grandma? The younger Mo Ran looked to be in her early 20's. If that were so, the present Mo Ran should have been in her mid 30"s.
- Ok Sun's husband. A character that the drama could also do without.
- This series felt rushed. The past of the Fl's should have been played out in detail so that the viewer would understand where they are coming from.

Positives:
- well the soundtrack was so-so.
- First time to see Kim Sung Ryung and found her to be really pretty. Would like to see a drama with her as Fl and no one else to fully see her acting chops

Note: To each his own. Respect. You can choose to agree of disagree. This is just my personal view of the show.
