I think romance is friendship and attraction sort of meeting together and that does influence what I'm writing a lot. I try to establish the attraction obviously but I also think it's important to show the characters having actual conversations about things other than their feelings for each other - and to develop their friendship on the page.
We can for example be fairly confident that either there will be a world without war or there won't be a world - at least a world inhabited by creatures other than bacteria and beetles with some scattering of others.
