This drama was so good.
Ji Na and Sa Na were sweet. Ji Na particularly was an awesome person and just awesome to everyone so she was probably one of the best characters I've seen. Also, I loved the contrast between Jae-i and Ro-bin and although they had the same upbringing, they're so different. The "villains" were completely on point and hateable. Rok Hui was dearly beloved by all the viewers including me (lolol) but I wish she had more screentime.
Also, I just have to point out that Jae-i and Ro-bin aren't twins lmao.
I would for sure recommend this drama.

SPOILER AHEAD
First off, I'm a bit disappointed that we didn't find out more about Rok Hui and her dad, since there was obviously something there. Especially with the reference to Rocky and Rok Hui's convo with Ji Na about it.
Second, what exactly did Ro Bin do in that club? Lmao. Also how did he get the fake ID? And did they ever find out it was fake?
Third, Its a bit of a shame I never found out who seeked the revenge for Ji Na, but what can ya do?
I hope there will be a Revenge Note 3 but at this point who knows.
