LMAO panel4 is literally copy-pasted from ch.53, with one very slight touch-up.
I expect to see this panel re-used several more time until Kashiwada finally expresses herself.

That was a compression artifact when I shrunk the size.
I know they're the same size because I kept tab-shifting back and forth to check.
If I knew how to make a gif, I would.
But I do agree that it would be amusing if the author slightly increased her mouth by a few mostly-imperceptible pixels every time, causing readers to doubt themselves.
