Summary
Kiara had learned when she was fourteen that her soulmate had died during WWII, so she was understandably shocked when he turned up during the Battle of New York.
Note
This is part of a new series of unconnected one-shots I'm starting in which an OC is the soulmate of various characters through several fandoms. I'm a terrible romantic and love soulmate tropes more than I probably should.
