Love with Wings

I'm writing a sci-fi romance where there is a tribe of winged hominids. Their wings are similar to those in angel lore -feathery and separate from their arms and hands. I worked out the mythos of how they came to exist but struggle with explaining why their wingspan is not crazily wide. Everywhere I researched, explains the impracticability of winged hominids because the wingspan would have to be quite wide. How likely would you -as a reader suspend your belief on why it's possible for hominids to have them and be approximately the stereotypical size of angel wings? Would you need the story to explain it?

I don't foresee it being a super technical sci-fi. It's more in the Otavia Bulter, Lilith's Brood vein of story telling. Or if I can use a tv show Doctor Who or Star Trek-ish . Some plausible science thrown around but not much

My story doesn't really have magic in it, it's a sci-fi. There is very advance technology which allows my characters to augment their bodies. They have the capability to augment their body through upgrades -not all have wings, just a few sects. The way my story is set, nearly everyone utilities the tech but not everyone knows or is interested in knowing the intricate details of how the technology works. If I could compare it, it's like how we all (or most all) have a mobile phone or have use a mobile phone. Nearly everyone who have used a mobile phone, knows how to make one work (more or less) -we know how to turn it on and dial a number. We may even know some little tricks to tinker with it if there are any issues (id est: poor reception means we need to move to another area to pick up better reception). But many don't know the mechanisms that make a mobile phone work. Or how to repair a refrigerator when it's broken. Yes we can probably google or youtube how to repair a refrigerator but most of us just call someone to fix it. In my story, the people could acquire the knowledge of how certain things work but they're lazy like we are and pretty much rely on the tech to build or repair itself. There are some specialist who monitor the tech but they don't necessarily go around explaining things in great details -it's like how a doctor may say you need stitches and tell you they are using dissolvable stitches so you don't have to come back to them to get them remove but don't necessarily explain how they stitch you up, what kind of material they use to stitch you, etc. I don't particularly want to make the focus on the science as its more about a romance but I don't want to make it too difficult science wise for people to suspend their disbelief...

Thank you all. I think I won't worry about the wingspan. I don't intend to sell my book as a hard sci-fi so hopefully readers won't have too high expectations lol.

lol yes this is my thought too lol. I know I personally don't get too bogged down by things in Star Trek, or Star Wars, or other sci-fi series. As long as there is consistence to the technology/magic I generally go along with it. Hopefully, I write a story worthy of people willing to suspend their disbelief and go along with the story.
