Natsu No Arashi! (2009) S1E03

Hajime and Arashi are flashed back to a world of the past and Arashi still cannot believe that she is a ghost. Now, even though weird things are happening at work, all Arashi could do was think about what had recently happened. In the meantime, Hajime advises Jun that there it's strange that a freeloader has all of a sudden appeared and that they should keep a close eye on her, as Arashi becomes increasingly more immersed in her thoughts about earlier.
