"The lady improper" is about the reality of married life and the psychological problems of the woman who is afraid of sexual contact. Because of that, her husband decided to divorce, so the main character Siu Man is trying to do her best not to lose her husband. But everything goes bad and her life is getting harder.
After divorce, Siu Man is in charge of her father's restaurant where she meets firstly a stranger but then he gets a very close person to her.

I'll try not to make any spoilers here, so if anyone needs recommendations for this movie I'll write my opinion about it.
Firstly, the movie is really important and shows us how hard can be relationships between a man and a woman who aren't personally close to each other, can't understand their feelings, and the cause of the divorce frequently is the facts that I already mentioned. The film director wants to show us what kind of significance has the sexual connection between married people. I think this is one of the most bearing things.
Secondly, what kind of interrelation should a man show a woman to make her trust in him and help her not to accompany fears and get her psychological state get better. There appears a man called Chia Hao who is carefully trying to become good with Siu Man. He knew she is mean and endeavors to get closer.
I think Chia Hao is one of the best characters in the movies that I ever saw. He is tenderhearted and respectful to all the emotions that Siu Man incurs. In my opinion, this is the real kind of good dependence that man can show woman. For her own, Siu Man gets addicted to good behavior and tries to put up with this kind of novelty in her life.

Finally, I think this movie is efficient to watch and I recommend it to you.
