I finished watching this drama few days ago, and no matter what I do, I cant move it from my heart nor my mind! I can't stop listening to OST and crying over them T_T I really wish if I could forget this entire show and re-watch it again! The main story is good, the drama catched me from the first episode, (I saw till 4 then stopped according to exams, then completed it all in a week xD) but some where at the 20s it got really boring >< anyways, if you forced yourself a little bit more, you'll find that this drama deserves! The focus on the main story started at near episode 36 or so, and from there on, this drama is incredible! (and also tear-jerker T_T) I loved the characters, my favorites are the brothers Dong-Chul and Dong-Wook even though in the middle Dong-Wook started to annoy me, but I understood him and sympathized with him till the end The music! oh don't even mention it, it is amazing!! I really care for ost when watching dramas, and this one has a really good combination of them. I specially like Fate Reverse by SG Wannabe, actually I am listening to it almost every day since the 4th episode of the show xD re-watch value is low since I don't re-watch dramas usually + this drama is really long! also I didn't heal yet from watching it T_T I'm sensitive person who got emotionally attached so easily, so this drama was kind of shock to me ^^" but I won't tell you to throw all this journey because of the ending, give it a try!
