This story takes place at their second year in Izumo when Ash will turn 20. They're a couple for around 1.5 years and happy. But for Eiji his promise of forever means until death separates them. For Ash, however, it means until Eiji will leave him. He only knows abandonment and is convinced Eiji will leave him, too, after some time. All the people he loved did the same, after all. Ash tells Eiji not to celebrate his birthday since his existence caused endless deaths and celebrating it feels wrong to him. Eiji is sad about that request but still promises him that they won't celebrate it and Ash assumes the issue is solved. Knowing Eiji's stubbornness, however, he should have known better... Instead of celebrating, Eiji gives him a present by taking him on a little trip and teaching him what unlimited freedom feels like. And that isn't all. At dusk, Eiji plans to ask Ash something that will forever change their lives. Something he meticulously planned for months... Will Eiji's plan succeed? A story about pure freedom, a promise and undeniable proof of Eiji's love that surprises Ash.
