This may not be the best lakorn I’ve watched but there is something in here that urges me to write my first ever review. Each and every actors/actress played their part really well. It conveys REALITY and teaches different life lessons about (1) different kinds of love between parent&child, husband&wife, gf/bf, sibling and friends (2) true essense of sacrifice (3) forgiveness (4) shows how anger, hatred & selfishness can make our lives miserable (5) awareness on emotional weakness leading to commiting suicide / depression / emotional breakdown —this one specifically made me realized that each one has their own level of tolerance, it may appear as small problem to you but could be a great suffering to others. (6) learning things the hard way — sometimes you have to taste the bitterness of life to appreciate sweetness; you have to lose someone/something to realize their values.
For the lowlights, (1) I find episodes 1-5 a bit dragging / boring...well probably the writer just want to establish the story since there are flashbacks but you have to endure to better understand the story. (2) The Ending, they say that if the story is nice they find it difficult to put a nice ending. They should have extended it a little, showing more scenes on how they are after reconcilliation, building their family, and for those who are still alive to finally start to move on with their lives and so on.
This a more serious and matured drama. But, overall this is really worth your time. So, I recommend that you give it a try. (two thumbs up from me)
