Advent Calendar babble, also Gravity Falls! <3

This Yuri on Ice Advent Calendar is quickly turning into a Otayuri Advent Calendar and honestly I'm okay with that. But not just Otayuri; this is some of the shmoopiest, most romantic crap I've drawn in a long time. Imma have to draw some porn just to balance it out tbh. And I already know exactly what I'm going draw ohohoho

I'm a little confused about advent calendars though; is Christmas Day the day 1 on them? Because every advent calendar thing I've seen is 25 days long. If they start on December 1st (and all of them that I've seen do) then naturally, Christmas Day would be included. But I always thought that since it was a countdown, Christmas Day would be zero, not one? Clearly, I've never done advent calendars of any kind before, lmao. But since Christmas Day is going to be part of it, on that day I'll have multiple pieces drawn for multiple fandoms. If I can manage to draw/write that much, haha. It's a lot!

I've finished season 2, episode 13 of Gravity Falls and I have some thoughts about it and also shipping ( Cut for spoilers I guess )
