I was actually expecting a plot where Qiu comes back and sees Pan is maybe smiling with someone else, but he decides to respect that and slip out of the bar quietly because he acknowledges that they’ve both moved on and gone their seperate ways. It might’ve been a solid, positive but quiet ending that resolves Qiu’s character arc of growing up.
The idea of the big promise to wait is romantic but it doesn’t really fit with the more subtle endings we’ve been seeing so far.
....But I’m also here for big dramatic romantic stuff, and I’m a sucker for this pairing, so I’m interested to see where this goes!
Edit: I also love that daydream!Pan is drawn slightly younger and less self-assured, while daydream!Qiu looks slightly older, closing the age gap a bit. Could be a slight adjustment to the art (or maybe I’m projecting lol) but the way it reflects Qiu’s thoughts about their relationship is interesting, even if those thoughts may not be accurate.
