Mated

Everyone has a tattoo of their soulmate's favorite animal. When soulmates meet, the tattoo glows, and when it dies down, the tattoo is replaced with a tattoo of both of their favorite animals together.

Unfortunately, Y/N is worried she would never meet her mate due to her tattoo being a common animal: a wolf. Now that she's in her 30s, she's accepted that she will never meet hers believing her chance was gone. Her brother refuses to give up on her, coming up with a ruse to meet a friend.

Bucky left Brooklyn for basic training right after high school, not wanting to face the possible fact that the girl he was in love with might not be the soulmate that the fox on his wrist indicates. He took a decoding assignment in St. Petersburg until he gets transferred to Moscow. After his train is derailed, he starts to reevaluate his life, as his soulmates tattoo was now wiped from his wrist. Worried that it wasn't caused by his accident, he rushes home to make sure the girl of his dreams was okay, and test a theory he has.
