Well did he have reason to be worried about Nam Ing? Have reason for her not to see Por? Like he said, I'm afraid, cause you and I we started as friends too, and look at where we ended up. I want more than friendship. She was ALWAYS with Por. As much as one wants to stay committed, closeness sometimes leads one thing to another. Only one person needs to act on those feelings and who knows what will happen next.
I dont think he should have cut all ties with his friends, but at the same time, as a married woman, you dont do sleepovers with single guys. It's just inappropriate period. Ask that on an english forum, on a thai forum, it's inappropriate period

She had her reasons, they were her best friends. But realistically it's impossible for a woman to do that, let alone think about sleeping in the grass with single guys in the middle of the night. She was pretty much a baby

Oil had to carry her all over the place
I really dont care if he has no room for his friends, I find it wrong he had no heart for his parents, but nonetheless, compare him to Por, he was much more of a faithful and loyal son than Por was. Por's love was rice, and farming. He destroyed everything his father dreamed of. Oil on the other hand was doing everything to make his wife happy. And he didnt step down, he went up the ladder. That's the difference
