Nao reveals that she is very young (just 16), and that she will die soon. Again, though she doesn’t directly admit that she is planning to kill herself, this is heavily implied. Since a “time being” exists in time, Nao uses the phrase “drop out of time” to describe death—she suggests that after death, one is no longer part of time. To Nao, whose death is around the corner, every moment is precious, since she doesn’t have too many left. Her reader and confidant is now so important to her that Nao wants to count down her last moments with them.
