It is very tough for me to be interested in watching a drama with unfamiliar actors - I thought Captain Yoo would come out early but he didn't so I thought of just dropping the drama. But as the story progresses, unnoticeably I'm beginning like the characters and feels good about seeing how they live in the prison and finally laugh and shed some tears.

The story makes me think how the world might be like if we have the mentality of a sinner who thinks he doesn't deserve anything so when somebody does him good - he feels humbled and grateful. It reminds me of how Jesus Christ died for our since while we were still sinners and how undeserving are we of his grace - but we received it anyway.
The story inspires me to be somebody who is capable and successful - Just as how KJH has means and fame, and knew exactly whom to share them with. How fulfilling is it to be able to help someone and eventually become family.
The story also makes me think how being in the unknown zone makes you discover things about yourself and how your character is built based on the responses you make with the help of people who believe in you.

*Spoiler*

And lastly - i think the reason why only the "DRUGIE" failed to learn his lesson - is a warning to viewers to never take drugs because it controls your brain - which prevents people and even yourself in helping you out.
