I really don't think Jua and Gun's dynanmic can be described as anything romantic to be honest, they're just as someone described it below, a pair of "dysfunctional siblings".
I hope so. But it's hinted mildly. Judging from the events that happened in this manhwa, you can't underestimate those subtle hints since those little details we take for granted can throw us off in the future chapters.
I love reading gaycest, but Jua is acting very pathetic. It doesn't matter if Gun ends up with seongwha or anyone but not Jua. I really hate their ship.
