FTLY preview for episode 22/23

I stumbled upon this, it says something about episode 23 in the title, but don't know if it's just a typo. Either way, this is a new preview released by Sanlih.

I think XY receives some letter asking her to come to the lawyer's office to settle her divorce or something, and there CX surprises her with his new chicken outfit... It looks kinda funny :) What I can't figure out though, is why XY is dressed so, formal..?
