[Shuuichi/Minato] Walking Together into the Future

Being yin-yang twins, you and I are the luckiest thing in this world. In the distant future, we will still be just as happy as ever. 1. A rewrite of the neighboring story, Future Together. It won't be locked for now, until this story catches up. Some of the romantic development has been rewritten. 2. NaruSasu skin rewrite, because it's Indra's birthday! Happy birthday! 3. I'll add the rest later.
