They totally changed the original script. In the original script, it was Oil that sent the gunman to kill Por. But looks like that didnt happen, he's totally innocent. The gunmen were sent by the other businessman to kill Por, but Oil took the bullet. This lakorn isnt just about greed. It's about friendship. At the end, during the meeting, Oil said, "i have enough money, but I want friends, I want love, I want family." so he chose his friends, he chose to love the land that fed him over the thousands of millions he could have made on that project.
So in the end, his love for his friend was stronger than his selfishness and greed. If he died purely on greed, it would be that the gunman was sent to kill him. But that wasnt the case, Oil actually chose to take the bullet for his friend. He wasnt in the way, he got in way to save Por. He died for friendship and love.
They didnt cut any scenes to reduce the episodes, it was scheduled for the 15 episodes, and according to P'Nuch it wasnt shortened. The only part I know they edited out was Por's confession to Jui.
