Ok so you haven't really said much about how much or what kind of feedback and guidance you want so let's just start from the beginning of the Covenant Chronicles and work through the first chapter and I'm sorry if this sounds harsh, but you've not given any guidance in what you want.
Firstly, you cover is fine, but nothing stand out, it could use some work and a banner is also pretty useful for extra polish. And that does seem to be the biggest issue I'm seeing straight away. Just no polish. It feels sort of uncared for in that sense, like you wanted to get it out rather than take the time to make it shine. You have typo in the first sentence of you summary.
After a frightening guns hooting
that should be gun shooting, right? Your summary needs some work. You've got one massive sentence to start that's overly wordy (one assumes a gun shooting would be frightening, and you probably don't need to specify that it's guns, just a shooting) and it doesn't tell me much of what to expect.
Your opening scene is awkward, not exactly enticing and not the clearest, which is kind of a problem when it's so short, so, working through:

As an opening line, this is really weak. Now, that's not the worst thing in the world if you can back it up with an interesting follow up, but you don't, but we'll get to that. You should have a coma after her, so "I tell her, knowing" but that's also just really clunky and awkward. I don't know who "her" is, and just straight out telling me she'll be happy it wasn't thrown away is the worst way to do this, especially over something I have no idea about.

The woman? I don't know anything about her. You're giving me all this information about a mum and her earrings and her two year old without setting up anything. And worse, you're just telling it all. I understand you're probably going for some kind of "this is normal" vibe, but you can't rush it like this. This character exists for maybe paragraphs (I think? You never say she leaves, but you never mention her again) and in this weird place where I know lots but also nothing. Also, "hides earing on his Mother behind the living room sofa." is just a mess of a sentence. This is what I mean about polish. Do you mean from his mother? And why is Mother capitalised? "I yawn" should probably start a new paragraph, since I assume the client has left or this is the rudest reader of whatever she's reading, you haven't told me yet.

So, yeah this should be its own paragraph from "I yawn". Honestly, you could start the chapter here and nothing changed. The entire first bit is pointless. If it comes back later, it's terrible set up, since there's not enough detail in it to have mattered. I still don't know what our protagonist is reading, or their name, or why it's tiring or anything like that. The "he, he, he" is personally grating but acceptable if you're going for that sort of casual style, but doesn't seem to match the rest of the prose. Also, generally written as "hehehe" instead or "he he he" the comas imply a pause, and you don't laugh like "he (pause) he (pause) he" do you? Read out loud, it helps.
Again, "getting my stuff" feels like it should be a new paragraph. New action, new paragraph. But then I don't know the timeline here, it's pretty unclear. Why is someone in the shop(? idk, you haven't actually given me any setting) a strange thing? What about this is strange? Is it her eyes? Then put that closer, because as it is right now, it seems like a girl in the shop is strange.
"Walking over without thinking:" is just wrong. She clearly is thinking about it. She's just said it's strange. If it was just a customer, go over without thinking, then notice the strange eyes (I'm still assuming that's what's strange) then that wording works.

So, this entire bit is messy. For a start "without thinking:" is not the punctuation you want. I think it's more likely you want that on the same paragraph and instead should have something more like this:
Walking over without thinking, I ask, "can I help you?"
She seems deep in thought.
"There's a sale today, what oils would you prefer?"
You do this a lot. You do a couple of things, you action tags don't like up with the dialogue properly. Again, the next part. When the girl is asking questions, they should all be in the same paragraph, if you want to do it like that, or all separated out. Pick a style and stick with it.
Then you've got things that make no sense to me with the context given. Why is it perfect that she wants protection oils? Because they're on sale? Because it's a customer? So far, the pov character has seemed pretty bored or tired of her job, so says its for the money above, so why is it perfect?

If this is your big climactic scene, it's so rushed. "Because I came to protect you" feels like a full sentence already, so the cut off is weird. "She says then as I blinked my eyes." is not a full sentence, I think you mean to connect it with the next one. A man in a hood just entered the store and started shooting, and you treat this like a throw away? One sentence, not even a sentence itself but shared with a woman disappearing? You spend less time on the shooting then describing the mysterious woman? Does that seem like the correct narrative weight to you? Especially if this is supposed to be some kind of antagonist for the story.
Overall, it's definitely not the worst thing I've read on Tapas. It's readable. I understand what you're trying to say and what you're going for. But it really needs a lot of polishing to make the most of it.
