That's such a weird question to me...it's like asking "do you have a work with no murders and why?" Like...it just so happens that the story did not need any. ^^;;; What other answer can I give...?
Maybe I just don't understand other people's thought processes when it comes to writing romance (I think on this forum the general sentiment is largely against it, so I haven't had much luck) but to me romance is a story element like any other.
Sometimes I want intrigue or horror or violence or humor, or romance. And sometimes I don't. It depends on what I'm writing. ¯_(ツ)_/¯
I guess it's a pertinent question because of how popular romance is and has always been, but I...don't care? ^^; I don't write to become popular OR to specifically avoid what is popular. I write what I like. No matter what goal I start out with, I always end up writing what appeals to me.
...It's very hard to find a good one. ^^;
There are only a few series I've seen where romance is not a factor at all...and sadly, that usually means that the important relationships that ARE in the story end up bland, lifeless, and unexplored. =/
I said once that certain writers "think platonic relationships write themselves", and as much as I hate it it's very true.
Apparently you can just have characters stand next to each other and say "friends" a lot and that's it...don't bother to write in moments where they think about each other's wants and needs or learn about each other or grow together or anything...wouldn't want to imply that non-romantic relationships can have depth or impact or anything...
Someone on Tumblr once wrote a post about this problem in The Bad Batch, and I was kinda mad at them at the time, but in hindsight, they had a point. ^^; In a story where the inherent humanity of clones is one of the larger themes, the glaring absence of 'camaraderie' and familiarity in the main group is hard to unsee once you notice it.
The brothers trust each other and know each other's skills...but that's pretty much it. Their bond is apparently not that much deeper than one you might have with your favorite weapon, or vehicle...even when one member is tragically ripped away from the group, all we get is brief mentions of "urgh, that traitor betrayed us" and nothing else. You don't even get the sense that there's attack formations or maneuvers they can't use anymore without him...it's like they don't really care that he's gone in any way that matters.
EXCEPT for Omega (who doesn't actually know him...), but I'm not gonna get into that. ^^; The point is, I just wish there was a better selection of non-romantic stories, especially among those geared towards adults.
