I always feel sad and after seeing any death in drama. But this drama show death of people like its very common. I think writer loves deaths too much.
Apart from deaths, everything was perfect. It's just that so many people died without any special meaning or effort or anything. While whole story revolve around Moo Young father's death. But they didn't give any attention to other deaths.
Me who love happy endings so much, I feel last two episodes were not needed, we can call it a happy ending just after episode 14.
Character Development
There is very little progress in characters.
Kim Moo young who is portrayed as bad but good person, who still becomes bad person at end who can be overtaken by his anger. Jang family both children were dead but still Moo young doesn't feel any remorse or anything.
Yoo Jin Gook is same throughout the drama, a very good person with a bad past. but still some points which did not even matched with his character like he stabbing Moo Young.
Yoo Jin Kang is the character I love the most, there is progress in her character
Tak is also a very good character which make this drama so lovely.
But still no explanation between Jin Gook and Tak has been provided like why they are not married when she is also good to Jin Kang.
