What does the eighth episode of Dark Glory mean?

After the man and the woman met, they both knew that they had reached the stage of extinction, but they were still ambiguous. The man asked the woman if she was wearing cold clothes, and the woman said, "The photos you took are the best." Look at that photo carefully, it reveals the abstinence and restraint of the man and woman. The woman seems to be hinting at the man, "I have an insight into your thoughtfulness under the cold mask, but I like it very much." Isn't it a little provocative and playful?
