Translation tools have a hard time with this font. It first suggested “acting partner”, then it thought it said “gardener”. I did some searching, and I believe it’s “theater partner”, as in this guy is her date to the theater(movies?), she realized she was overdressed compared to him, and then traded clothes with the other woman.
I see what you mean, she has a different expression, more confident, and her hair looks more wild.
With the dress she’s showing her waist and bosom but the style looks a bit outdated for us now.
Totally agree the guy is hot haha
