    I pass on this. Sounds boring and the choice of actresses moved me.

    Sounds very promising–looking forward to this! (Full disclosure, I would happily watch Yoo Ji Tae read the phone book). But looking forward to this FOR REAL!

    at first, i didn’t really care that much about the drama from reading the synopsis. then when i was in youtube, i happen to watch mad dog ost and it kind of motivated me to watch the drama >u< and its a good thing i did because this drama is like a masterpiece! the pace is not too slow not too fast, everything falls into its place. it feels like i watched an hour of episode in just five minutes! also i really love ryu hwayoung and woo do-hwan chemistry♥♥♥

    Woaa guys you have ti watch this drama, its very nicely done, all characters are not boring, I live for Jang Hari and Kim Min Joon moments …. but dont expect to much on them…this is not a love themed drama… all of the viewers cherish their moments…it might me small but its very heart warming because both of them are very tough…this drama keeps getting better every episode…its not your usual drama, it also has a family touch, action scenes, relevant events(INSURANCE FRAUDS) and many more!!! JUST WATCH IT ALREADY!!!
