I agree! While it could be read as romantic, neither Korra nor Asami have been seeking out a romantic relationship with anyone for quite some time now. It felt like we were witnessing an intimate moment between two characters but there's lot of intimate moments between friends. Intimate doesn't just mean "sexual". I think they're just looking forward to finally getting to relax, to just be young women and enjoy life. If that means they'll do it together as lovers, good for them. If it means they're doing it merely as besties, good for them. Either is fine with me. I just think that, Korra especially, romance has been more of a tiny subplot for our main cast then the actual focus. Bolin has been the most driven by it, whereas the others kind of let it fall away in favor of the mission. And honestly, I felt that Korra's last moment with Mako was ALSO semi-romantic.
