Actually, he didn’t mean to travel with these 2 girls who he knew in same college. He was only about to guide them to a cheap place to stay in LA since they met by chance. But now they are staying in same hotel in separate room. They went to observatory on mountain together to look down the whole LA downtown.
He asked a middle aged woman to take a picture of them. He was in the middle between them. Just before she takes a picture, he hugged them with each arm, trying his best to make a smile and look cool. But it did not come out as he expected. His eyes were not smiling, and face muscles moved arbitrarily.
