I was initially intrigued because of the actors in this drama. I really liked it, but like many others have said it did seem to drag at parts and probably could have done better in 16 or 17 episodes rather than 20. I also felt like it was REALLY cheesy at some points, as in I thought to myself "Okay, this would never happen in real life, but I will accept it for the purpose of it moving the plot along of the show." I guess that's why it's called a "melodrama" though. On a more positive note, this has probably one of the better OST music I have heard in the few dramas I have watched! It's played a little too much, but I guess that is to be expected when it is so short overall. I also think there may have been some cultural things I missed as well. It must be a "taboo" to like someone who **might** (not spoiling), become your step-sibling even though you're not blood related? I don't know, it just kind of aggravated me because to me I saw nothing innately wrong with it, and that seemed to be like 90% of the problems our 2012 characters have. Finally, the acting was great though! Yoona and JKS were so cute together at certain points! I would love to watch another drama with them acting together. I do feel like they could have done more of development with the 2012 charters (Joon and Ha Na) though. It felt like less of a romantic relationship in reality where you get to know each other for a while, but instead in this there is a kind of of "instantly falling for someone" thing going on. In any case, I am a just a sucker for a good story and I enjoyed it for a bit of a mental break while I was on a break from school! :) Enjoy!
