I like the concept of this drama, it's like watching several dramas in the price of one. You get 2 major love stories, 2 smaller ones, some family drama, bromance, revenge, redemption and even a bit of action. The plot is so complex that you really can't get bored while watching. I really admire the writers for being able to intertwine so many stories together. Throughout the whole drama there are new characters appearing, some disappearing for many episodes to appear again and new connections are revealed. Even if you are able to predict the eventual outcome and some ideas are something you might have seen before, you really cannot predict when something new will be added. At some point I was a little bit worried if they will be able to wrap up all of story lines, but they did a great job with that too and the ending is very satisfactory. I really liked most of the characters. Female leads were really awesome and that doesn't happen too often in dramas. I really love Ja Eun - she is one of my most favorite heroines now, Soo Young was also adorable - hard on the outside, but very soft and warm inside. Only characters that I didn't like too much was Soo Young's parents, maybe most of their scenes were there for humor but I've found them a bit annoying. And I really love, love, love Ja Eun and Tae Hee story! If you like romance, I suggest watching this just for them.
