Can their young love withstand the test of time? Against the backdrop of idyllic Okinawa, two people find their lives inexplicably entwined in a story of a first love that spans 15 years. Adventuring out on her own, Mai travels to Okinawa in search of her real mother and happens to meet Kota, a hostel clerk, by chance. Equally turned off by each other’s different view of the world, they eventually fall in love. But fate has other plans as a dark secret hidden by parents and a friend’s dire situation are only the first of many obstacles that they may not be able to overcome.
