Usually, Foggy Nelson is the textbook example of the Decent Boyfriend. If he's attracted to you, he will TELL you instead of pining, he will respect your boundaries and make sure to communicate at length with you and it's all terribly, terribly rational and responsible. Safe. Calculate, even. Mind over passion.

With two notable exceptions: Marci Stahl, who makes Foggy's dick speak louder than his head, and this stupid crush he has on his best friend and business partner, of all people - the kind of crush that has him pining and suffering quietly in sweet, sweet torment, and makes his heart flutter like he's 14 again and scribbling "Matt + Foggy" all over his diary.
And he just can't get the words out.

I'm a sucker for Matt/Foggy and that's mainly what I'm looking for (can be unrequited), but feel free to focus on Marci as much as you like, I really adore her.

Bonus:
Foggy knew he was fucked from the moment his ridiculously attractive new roommate sounded like he was about to rebuff him, and instead of saying something like "Hey, it's okay, didn't mean to make you uncomfortable, hope you don't mind sharing a room with a bi guy?" he started blabbering some bullshit about picking up girls.
It all went downhill from there.
