In our society, everyone carries a huge burden; when we see someone, we also see a date attached to them: the day they die. The only problem: when we look in the mirror, there is no date attached to us.
No this has nothing to do with Death Note. It was based on a Tumblr post that asked people to write a story in a world where people could see each others' death days but not their own. Meaning that everyone can see how much time other people have till their death. But unfortunatelly no one can see their own dying day.
