Working in a bento shop, Arata cannot help but be curious about Shun, a young boy who regularly comes to buy food. However, he stops appearing all of sudden. One day, Arata awakes in the other world after saving a dog from drowning in a river. He has to stay in a hotel before passing on—and out of all places, that is where he meets Shun again! A heartfelt love story about a lethargic guy and a straightforward delinquent that unfolds in the afterlife.
