she did love him. her "dettached personality" is just how a queen is supposed to be. she was raised to become queen and naturally she became the embodiment of a queen. spoiler
sovieshit attends her wedding day. he gets drunk that evening and begs her to return to him. this makes navier cry because she really did love him. he was a totally different person before. you know that type of love you have for someone despite their flaws. thats what she has for him. tho not for long because of heinley

I think she did at one point, especially since she felt hurt when he brought Rashta in. I just think she chose being the empress, which was her duty, over her love, so it wasn't seen as much. Whereas, Sovieshu was the opposite. Instead of taking on proper duties of an emperor, he was more childish in trying to express his love and wanting Navier to do the same. I think they loved each other at one point, but grew apart because of different interests and views on their duties (Navier ffg does hers seriously and Sovieshu slacks off).
just to clarify: navier and sovieshit love each other. but we all know who's the dumb fck between them
