I would've been disappointed if they didn't decide on cross-dressing for this occasion.
1) Trick Situ Xia? You mean, the crossdressing general?
2) I really do hope there's the banquet and the wedding will be on a different day, otherwise we'll have the princess marry Situ Xia. And the general prince will marry the brother.
What a mess.
But that's why we love this story.
Thank you for your hard work <3
