It took me a minute to figure out this is one of those "spot the differences" things. When I was trying to figure out what was the deal with the 2 images, flipping back and forth with the "back" and "forward" browser buttons between the two images made it a bit too obvious what changed, so try not to do that right away!

From Top to Bottom, all differences I can find:
1: The sign above Piece has a different character.
2: There's an extra bowl on the countertop.
3: The leftmost menu item is different.
4: The dial on Yoshika's heater is turned differently.
5: The flower between Youmu and Kutaka has a different number of petals.
6: Yuyuko's Squiggle is flipped.
7: Cirno's glass is drained.
8: Youmu's tie changes. (this was the hardest one to spot for me, it was driving me nuts).
9: Aunn's utensils change.
10: The slug has moved forward a bit.
