The one who caused the most problems was the FL herself, acting like Pat & Mat(if you see this stop-motion animated series)
If you like this animation or if you think that a dog Goes around to looking for its tail, It is funny, So you should see this drama!!

Talk and talk, About the game of chess,
They want to refer to attack and counter-attack and intellectual game in some way, But nothing is seen from the FL.

From the beginning to the middle, the FL's Mother tells about her son-in-law's betrayal, Again, nothing is seen and she talks about it without evidence.
And she gets sick just when she has to go to the hospital because the writer needs it.

From the first until the end all actions of FL is meaningless.

The very meaningless action she did in episodes 6 and 7,
After realizing that mistress had deceived her brother,
Why did she bring her to the next house? And remained silent
Despite the fact that her brother will be hit hard by this

Having a remarriage party, which was very pointless and provoked the mistress and Husband, and what happened this night.

The murder document(the knife) was right in front of her and mistress was alive and they could hand him over to the police
But she did not use it and plotted to kill her husband.
Why Killing him?!!
we see in many drama very very bad guy but eventually all say forgive him or they maybe after much hard work to collect evidence to apprehend, send him to court.
But why here immediately want to kill him!!?
.

.
But do not get me wrong, as I said at the beginning,
if you like that cartoon and funny dog, So be sure to watch it.
This drama is entertaining,
But know that all FL's doing is meaningless and is Just to move the story forward.

As the first work, the writer and director were not bad and showed that they are talented, but their work was very flawed and not cooked at all.
