Unusual Reaction (Yoongi)

When a werewolf first meets his or her mate, there is an instant connection between the werewolf and their mate which can bring them together across a crowded floor and make them feel as if no one else in the world exists. Yoongi can't wait to find the woman who will be the love of his life. He has spent years looking for his mate, only to finally find her at his brother's wedding. Ecstatic that he has found her at last and eager to talk to her, he becomes confused when she abruptly walks away, as if she had not felt any connection at all. What could be the cause of this most unusual reaction?
