You met Stanford back in college. It just so happened that you were in the same class. And it just so happened that after hanging out together for a long time, you were hopelessly in love with this idiot.
Stanford was smart, incredibly smart. When he got a grant and decided to go to Gravity Falls, you couldn't help but agree to go with him as his assistant. There, Stanford showed you that your world wasn't so simple. Gnomes, trolls, an endless pit and other delights of weirdness - Stanford literally changed your universe, bringing a different meaning to it. Gravity Falls was one big mystery, the solution to which you searched side by side. But no matter how far-sighted Ford was, he was far from noticing what he was doing to you.
The more you did research together in this cozy cabin in the woods of an eccentric town, the more you loved it. And you weren't embarrassed to show it to him, his misunderstanding was as charming as it was painful. Ford took your concern as a friendly sign or didn't understand it at all. Well, let it be so, the main thing is to be together with him.
