During the hours of the boys in the forest, their father was unsettled. He was really disturbed because he wasn't sure of how his sons are fearing. Though he haven't been to the ancient forest, he heard about the kind of dangerous animals in the forest.
On sighting the returning of his sons, he was the first to stand up. He rushed to hug Lam and tears of joy rolled down his eyes. His family is now an important figure in the village. They can even become king in the future - anyone that does such sacrifice for the village become possible heir to the throne. It was from a twist of celebration. He was happy they went for the adventure seeing the positive outcome.
