To be honest, I'm not a critic, and know very little about actual writing, and am still very much an amateur. But I'll say what attracted me, put me off, and generally, my first impression as a reader, so take this with a grain of salt.
First of all, I think you should have given the protagonist more attention in the synopsis, as we know nothing of her except that she's a writer and will soon be thrust into a life-threatening situation. In fact, the protagonist is only mentioned when you click more to expand the synopsis. The average reader, will most times skip the work when they immediately see a paragraph of exposition at the synopsis's beginning.
I think you should also add a lot more tags, as it will aid a LOT with discoverability, and because most readers like to know what they're getting into. Only a few readers would be willing to go in blindly.
As for the contents of the story itself, note that is a biased impression. I felt somewhat confused because you didn't properly establish if it was a cyberpunk setting, or a modern era transitioning into a cyberpunk era. The MC felt a lot of disgust at the consumerist atmosphere and whatnot, but you never told about where she came from to establish a comparison as to why she feels this disgust.
The MC herself hasn't shown enough to be likeable so far, apart from worrying about her sister. Most of what she's been doing whining about a new job she herself admitted was good, which feels a bit contradictory, showing disgust for Wildcore, when she most likely knew what she was getting into when she moved in, and closing the elevator doors on a dude who was probably in a hurry too, and showing no guilt whatsoever, that low-key pissed me off.
I didn't feel any personality from the dialogues too, and it overall felt bland, which might be a problem of you translating it to English, that might have erased your voice as an author.
You didn't describe the things in the sky much too, apart from saying they were triangles or drones, and I think you should have focused on the tension more, after all, if I'm right in my assumptions, this is strange, alien stuff, MC and her sister shouldn't have brushed it off so quickly.
I think the rest of the third chapter was okay, except the "whistles" sound effects you used, it might have underscored the impact of the hits.
A lot of your intent might have been lost in the translation to English.
Do remember once again that this is a first impression, and might even come off as shallow, but I hope it helped.
PS: This is a bit extra and maybe unnecessary, but I'm African, and the constant mention of the "African love story" she was working on, or the mention of the "illustration of the African couple" did rub me up the wrong way, even though you might have meant no harm and thought nothing of it. You could remove that part of it if it serves no purpose to the plot.
