Oh boy

Kanae grew up with the very strong assumption that she'd be married to a man. Her parents were in an arranged marriage that thankfully ended up very happy (and lovey dovey which one wouldn't really expect from the outside) so she grew up thinking she'd be in for the same. She was engaged to a young man from a minor vassal family to Hien's, but after a year the two of them broke the engagement off with their parents' blessing. After that she tried not to think about it too much, and even after being with Y'shtola neither of them really thought about it until a very incensed Tataru insisted they do SOMETHING... which they did. No wedding rings but they do have matching bracelets uwu

W'htal meanwhile, putting aside Seeker culture not really seeing marriage in the same way other peoples do, never even entertained the idea. Mr Serial Relationship Haver was fully content staying that way, and even after deciding to just be with Thancred and Urianger, he didn't even think about getting married... however all it took was one wayward glance from W’htal at a newlywed couple while the three of them were in Corvos post-6.0 for Thancred to ask him if he wanted to get married ""as a joke"" and god it's the most embarrassed either of them have been. Urianger had been in town and came back to the two of them not able to make eye contact with each other. After being told what happened Urianger just says "do it, I don't see anything bad about this" so they take a detour to Kugane and all THREE of them elope and get married by Tansui at the Shiokaze Holstery. No one really questioned his authority or lack thereof to do it, but boy did W'htal's old coworkers just. Stand there in disbelief while the husbands were drinking their asses off. W'htal called in a quick favor with another former merchant buddy and got some really nice simple bands as their wedding rings. W'htal and Urianger wear plenty of rings as it is so no one notices right away but Thancred wears his on a chain as a necklace under his armor.
