I love this sooooo much. And it's very much corroborated by canon. I mean, even in flashbacks to them at Marauder age, Sirius never noticed the girls checking him out, really only paid attention to his friends, but was loud and brash with them. I mean, I get that people want to correlate introvert with shy, but I think that's bull. I'm a serious introvert (off the computer, where people can actually see me)but I'm not even the slightest bit shy, just really really awkward. So I love this take on Sirius.

And Remus as well, I mean, he's really good with people, all people. He's just not loud about it. I mean, honestly, how many introverts would be able to teach? Way too much attention on them.
