Why assume that?
Interesting evidence to consider, though: We saw Grumpy decide against pursuing Nova in “Dreamy,” but when he’s first talking to Snow, he mentions he’s in George’s cell for buying a stolen diamond for the girl he loves.
So THAT might be relevant timeline wise.
I wanted to give the Yaoguai adventure a fair amount of time, but the time she’s actually with Mulan is not really that long. So most of the time would be travel time–yet in the time she’s with Mulan, the guys she ticked off manage to get to Regina and Regina manages to find her in the woods. So I don’t think it’s more than about a week total.
