Date Scene with Zhuang Fangyi

I'm just continuing with the story of Wuling and I went through the scene where Perlica and Chen leaves us alone with Fangyi after the experiment with Xiranite and seriously this seemed like a date scene between Endmin and her. Walking around the city, watching the blooming flowers, buying a balloon each, her narrating about the old times (that protagonist doesn't remember) and even taking Endmin's hand when chasing a robot with clearly camera angles to show this in a romantic comedy way.
I mean they even had a firework show at the end of the date with some special illumination being set to please the crowd. Kind of a contrast considering the city is supposedly one step away from disaster.
I'm not sure what kind of relationship Endmin and Zhuang Fangyi had in the past (maybe they'll talk about it later), but it must've been quite a close one. Are they trying to ship her as a possible romantic interest? Curious also to know her age to be honest, I'm guessing late 20s / early 30s is the most likely bet considering the time skip since Endmin went to sleep, but they seem tight lipped when it comes to this.

On gameplay news, I haven't looked in detail at the new structures needed for Wuling yet, but the first few I've seen in action don't seem much more complicated than the Valley IV ones. The tube/fluid connection system is cool and could be interesting to see how to keep the interconnections working once the entire map is filled with facilities.
