Kinda want this to be pure action and fantasy , it'll be out of character too. And they don't really have like, chemistry together ? Like some kind of notable history. You could say that her tribe helping her and hoping he becomes her husband is enough history but I feel in that case Cain (forgot real name lol) has more chemistry and history with the brother with the amount of times they fought lol. It just seems boring too with the lack of chemistry XD id rather the focus be on the sad brotherhood he has and his revenge than out of place love or him building , as I think he mentioned in the webtoon, a sibling relationship with the horn tribe siblings , and the red and green haired guys , and the blue haired kid from the first trial. Wow im thinking way to deep into this and getting off track XD
TLDR she's boring and flavorless and a romance with her would be misplaced tbh. Sakura level outofplace
I would agree with you with that I usually don't like romance in this kind of genre but I think it's kinda necessary with romance but at the Same time not really but any candidate is good as long as he can be together with someone we all know revenge is not any good and he's getting emotionless in my perspective when he cried in the Phoenix it kinda shows there ofc you can stop being emotionless with friends everything but then again you never know when will your friends betray and for me there's a special bond between a person that you love just like how he loves his brother

Curious here, does Edora and Yeon-woo ever get together.
