This is one of my fav dramas ever. I rewatched it a few times and it's always touching. The acting of the cast is great (especially Lee Ki Young),fighting scenes are well done, the plot is engaging and never predictable, the psychological profile of the characters is well defined,in that way you can impersonate with one of them. Old school drama perfect for those who're looking for redemption orthose who want to believe that each of us can improve. Inexplicably underrated drama, but give it a try, you'll not regret it!
