I meant to comment on this when it was posted and I forgot. This makes me think of surveillance, I think it’s the angle of Belle’s photo.

Anyway, Gold could be a cop or a private investigator who is watching Belle. Maybe if he’s a cop they think she’s their way to crack whatever case they are working on, or perhaps it’s a dark!Belle story and Belle is a criminal herself. Alternately private investigator, perhaps somebody wants to know everything about Belle for some reason.

So Gold is watching her but surveillance is boring and requires lots of coffee and takeout. One day he accidentally runs into her at the coffee shop while fueling up, and suddenly he’s getting a far closer look at her life than he’d planned.
