Although ultimately, I did really enjoy this series, it was a bit hit or miss with me. To start with the great, Seo Hyun-jin. Although her character was irritating at times, she portrayed the part excellently. I also enjoyed Kim Mi-kyung. I've only seen her in 'Mother' roles but she plays them perfectly.
The story concept was really interesting and I thought they did a good job with the two Oh Hae-young characters - one becoming insecure because she was constantly being compared unfavorably with her name-sake and the other being {mostly} oblivious to how her popularity affected the other. And I thought they did a great job with the makeup for Seo Hyun-jin in the flashbacks to make her less attractive. Of course they couldn't really do that with the 'present' version so the unattractive vs attractive comparison didn't really work for the bulk of the show.
And the theory of behind the 'visions' was new and interesting - I haven't seen that one used before.
I thought the ending was a perfect wrap up for the series. Especially the scene where everyone is together and starts arguing about dates.
As a side note, I always do find it amusing when they have an Idol-turned-actor sing poorly in the karaoke scenes.
But there were parts I didn't like so much. The drinking and drunk scenes were a bit excessive even by Kdrama standards. If real life in Korea is even a little like what they portray, liver transplants must be right behind cosmetic surgery in quantity.
And the leech-relative trope is one of my least favorites - just cut them off and out of your life already.
I also thought just-Hae-young's unrequited love for Do-kyung was unexplained. Sure he did a few nice things for her but her also was rather harsh in pushing her away. And while her background would have made her rather insecure, I don't see why she'd keep throwing herself at a seeming brick wall the way she did. Especially since, in the grand scheme of things, Do-kyung was the villain behind her latest set of issues.
