Definitely Zhao Yunlan's flat. ♡♡♡ It's such a HOME in every way, and the stools for sprawling are A++, and also I love drawing his bed, lol. I could just vote for it alone, but I didn't want to leave out other things. :D :D :D Like the main room at the SID (with the couch that I also got to draw :D), and Shen Wei's office (which I didn't draw yet?, but it has fish and it's so neat and shiny :D), and also the pillar because it's COMPELLING, lol. Oh, and other - the cliff in YOHE (which idk if it counts because it's a natural location) and the little square that Xiao Guo likes (which I guess counts broadly as Dragon City streets, but I'm still singling it out). :D

The second question is SO COOL, I've never wondered about that, and now I'm a big fan of the explanation that he's looking for Shen Wei's benefactor. :D
