A lovely little novel which could be read as a collection of short stories. All take place with the same cast of characters, collected together by chance and circumstance, in a cafe where it is possible to visit the past. Kawaguchi explores reasons for visiting the past, all the rules (like, the present will never change) make the novel solely about the emotional journey of the characters, rather than technicalities. It is lovely, and while based on regrets or longings it's uplifting; the take away is that you can always change the present, and most things can be solved by that.
