It actually seems obsessed, not natural, to do all that blogging and documenting. It means his mind was constantly going about his plan even though he was meeting new people and such. I don't know, seems contrived if you don't realistically try to let go and live a normal life, and then see if 1000 days later that strong love did survive. If he kept nurturing the love by dedicating his days to documenting, what's the point he's proving?
