I liked this drama a lot.
I loved the main character and I think that he had so many lessons to give; you should not give up on your goals, don't forget your values though it might be tempting at times, you may have a lot of things to learn from your enemies, accept, trust and support the people around you, don't think people are your enemies just because they do something that seems to be against you, because they have their own goals and that sometimes there are situations where you should forget about what you think is right or fair, just because you value a person more than that. His character and presence was indeed shining.
I would describe this drama as a story about ethics and life values. It also touched on so many issues in the society in a very fresh way, setting an example. I will always recommend this. It doesn't have a lot of romance, so it is appropriate for all ages. You should give it a try!
