"The story of Hana and Ro is… a fight, a supermarket, lots of spaghetti, a disgusting bathroom, an electronic piano and far too many plants. It’s messy, clumsy, but it’s also beautiful. Above all, it’s obvious. So much so that Hana thinks it could last forever. And then, on August 31, Hana falls asleep peacefully beside Ro. When she wakes up, Ro is gone. Gone without a trace. Gone, with no one remembering her except Hana. As if, in the end, Ro had simply never existed. Who really is Ro, that mysterious yet so lively girl?"
