'lucky one' or "the lucky one" is a term describing the person most fortunate in a particular circumstance or relationship
For Example: Mara is the lucky one, because Jessie is super funny, has cool hair and always treats her like she's the best girl in the world, even though she's a big nerd. It must be great to have such an awesome boyfriend.
