The movie does not show a bit of the sexual life of the uncle and Ploy as a couple. The only time Ploy took the initiative to kiss his uncle, the uncle said it was late at night and had to do it in the morning tomorrow, so he refused. But then I heard that Ploy was pregnant, and I was still very excited. Why?

Why do these beautiful girls that the uncle married later look so unbearable when they see boys from outside? Some of them even go to the house to seduce them in person at night. Why? The butler said that the old man was a wretched man who married many young girls but played with them all for half a year, and then rewarded them to the servants. Why?

Generally speaking, people have to hide their weaknesses and usually like to pretend to be strong to cover up their weaknesses. The uncle's shortcoming is that he has always had abnormal feelings for his nephew. So he keeps marrying beautiful women and becomes what everyone calls a wretched man. No one will notice his abnormal tendencies. At the same time, he has to suppress and avoid such abnormal emotions.

So when he knew that Ploy was pregnant, he was happy, feeling that he had defeated the evil obsession and finally had a normal life trajectory. It also explained why he was so heartbroken when he later learned that his child was gone, and why he was so angry when his nephew betrayed him.

In the end, he was unwilling to forgive the two of them, until he died, he was crazy. In fact, the shackles are all imposed by the uncle on himself, constantly expressing himself that he should hate those two people, because those two people unforgivably ruined his normal and happy life trajectory.
