Honestly don't see where people get the pro or con LGBTQ vibes from the story characters, there's not a single open LGBTQ character in the game.

There's barely straight affection showing anywhere between characters outside of families and friends.
Besides failed romance (little sun as example) acting as joke material there's no "feelings" displayed or expressed above firm handshake levels.

I've been questioning why there's no pregnancies or surprise babies in the game. Nation leaders like Nanamo and Hien should have heirs by now.
(Gulool Ja I guess, but he's not made out of love and that's his tragic arc)

But about LGBTQ, I never felt like this was meant by the writing and more a narrative that the community pushed while over analyzing and theory crafting.

Besides, you cant write LGBTQ into pertinence for a plot because China will block anything about homosexuality, probably other places too.
