She will be his wife but at the very very very end of the story. The novel doesn't focus much on the romance, and even if the manga does, it'll be okay since both of them are pretty cool and understanding, and their interactions are mostly like best friends finding relief in each other after fighting scary monsters. They trust and respect each other, so no worries, there won't be any cheesy romance going on.

You can read the proper translation at boxnovel, it's updating daily now and currently at ch 155.. I read the whole thing till ch 260+ at readlightnovel WHICH I DON'T RECOMMEND because I don't understand most of the storyline XD machine translations are just too weird, I feel like having a stroke just by reading them
I didn’t read the novel, but from what the others are talking, that vice-captain will be Jinwoon’s wife. Is it true? What kind of personality she have? I can see she is strong, but I don’t want a character with a queen level of arrogance, I hate it. And I don’t dislike romance but I don’t want the story to focus too much on it, like what happened in others mangas, where they force the main couple to confess and become a official couple, or use too many chapters to develop there relationship. Even worse would be if this two starts to be lovey-dovey. It would be good if it was like Erza x Jellal or Ochako x Izuku or Tsurara x Nura.
