I get that Anno and Kaede are in an open relationship but isn't Kaede already married to the cow-cat and has a kid with said cow-cat?
She's not married if I remember all those Savin stories correctly: cat friend got treated, Kaede fucked cat friend (sorta kinda accidentally), cat friend disappeared, and 9 months later cat/doggo baby is born.
This also made me realize apart from Embry, Emmy and Kiro, AFAIK Steele holds no special place in anyone's heart apart from being a good dick/pussy and or fits desired traits they're looking for.
I mean, I hate to bring up SYRI again (not really), but I'm gonna bring up SYRI again.
This may just be me and my love of said puppy-slut, but she's seems like a good candidate. It's kind of obvious she sees Steele as more than just a fuck buddy. The way she calls her sister a pussy-stealing bitch. The way her constant hard-assedness seems to fade away when Steele's around/involved, her opening relationship scene (the one where she asks Steele "out") specifically. The pecks on the cheek whenever you talk to her at the bar. The post-coital snuggles, you don't knot cuddle someone like that unless you mean it. Again, this could all just be me making things up because I like SYRI so much.
Edit: forgot to mention how she slams into the hull of ship hard enough upon land in Mhen'ga to set off a collision alert.
Did I mention I like SYRI?
