It was a promise that they made when they were just silly little children. Their pinkies linked together with goofy little grins on their faces as they promised to be to always be each others one and only. Oddly enough, that promise caused their hearts to magically link together. No matter how close or far apart they were, they would always be able to feel the pain the other felt if one of them were in trouble. What happens when Sasuke finally leaves the village though? Will either of them discover the reason as to why their hearts are connected?
