Jillian is a bit of an imposter – she’s a dating advice columnist, with little to no actual experience.
With every man she meets that has any potential for dating, she’s unable to speak to them.

Until she meets Daniel.

Though he doesn’t really have that potential either – since he’s a ghost.

He’s the only man she CAN talk to, and they start to think maybe he’s there to help her with her love life, and also her failing career.
