The theme could have been more developped, but I guess the budget was very very very tight, everything was tight even the end which was exactly the same combinaison of scenes and song we saw at the beginning. Conclusion: the feeling you get while watching this drama is the same as taking a walk around the corner just to go outside a little bit...so, how was your walk really depends on how was your day at work or in general, and how was the weather. What you learnt watching this drama is that when you have a tight budget, just stay frugal and keep eating the same fried chicken while listening the same song.
