This series is a must watch. The issues tackled, such as family and the dynamics of relationships between parents and child, between mother and child, between father and child, between siblings, between lovers and friends, were all well written. The conflict between the social strata of rich and poor was also very well executed. The only thing I do not like is the lead actor playing Dogyeong Choi. His acting is so amateur, he does not belong or rather deserved to be cast alongside Shin Hae Sun who plays Jian Seo. The others were exceptional too especially the actor who played Taesu Seo. The supporting cast were also very good. To the casting director you did poorly putting Park Si-hoo to play Dogyeong Choi.
