Choose your destiny (слэш)

Steve Rogers had been waiting for his soulmate for a lifetime. And was still waiting. Actually, he was sick of waiting, if they didn’t want to find him, that was their business, but he couldn’t wait around any longer. Not when a cute guy just moved into his apartment block that he wanted to get to know better.
Bucky Barnes had spent his adult life trying to find his soulmate, and although he didn’t want to give up on his one true partner, it was disheartening. He was starting to think that maybe he should take Natasha’s advice and meet new people. Like the cute guy in the apartment block he’d just moved in to. 
In a world where your soulmate’s vision is overlaid on yours at different times, and finding them can prove tricky, will two weary men whose other halves seemed impossible to locate, find something together instead? And what happens when their soulmates seem to be closer than either of them expected?
