I really wasn't sure what to expect from this drama, as I myself don't put much stock in the whole signs of the Zodiac thing, but I actually really liked it. The casting was pretty good. Mi Roo was not quite as good as she could've been, and I wanted to strangle a couple of the men she dated (because of the acting, not because of the story), but aside from that, everyone else was well cast. The actors who played Kwan Woo and Tanya did a particularly good job, but Jin Oh was really good too. As for the story, I will only say this: this is a fluff drama. I mean, yes, it deals with some heavier issues like finding true happiness and willingness to change for the person you love, but besides that...it's all fluff. Without giving spoilers, I can't write a review of this without mentioning the plot twist at the end. This particular plot twist by all rights should not work, and yet it does. The abruptness with which it is thrust upon you makes it a little difficult to accept at first, but it quickly slides into a more natural feel, giving you that feeling that this is the only way this drama should end. I am definitely gonna watch this drama again at some point in the hopefully near future.
