I checked out the first two chapters, and though they were fairly well written, they didn't hold my attention for a couple of reasons.
First, there was a lot of descriptive writing. A lot of time is spent describing settings in what I personally feel is too much detail. I'm not going to remember the petals in the water and the fountain in the bathhouse, or the specific layout that was mentioned in regards to where it's located. Centering the story on the characters, not so much on their surroundings, would probably help. As it is, there isn't much characterization in the first chapters.
The writing itself is good, but a bit wordy, or just oddly worded. There's also a lot of very long sentences. That, coupled with all the new and fantasy names/titles/etc. had me stumbling now and then. Tapas feels more like a place for quick reads. People open the app during a break and check out a chapter or two, which is why the chapters are meant to be short, so they need to flow smoothly and have something to make people read more. The wordy style also slows the action down to where it's not really suspenseful and I sort of lost what was happening.
The ending for the first chapter fell a bit flat, especially given the way it started. The first part was interesting, but then the suspense you built was ruined by the bath scene that slowed the pace of the story. By the time we get the tease of danger at the end, it feels anticlimactic. This also applies to the chapter as a whole. We're given a glimpse of something intriguing at the start, but we don't really get to see how it got to that point by the end of the chapter, or how it all even ties together, so we forget that was even there and nothing much happens the rest of the chapter.
Ideally, you'd want to have the audience invested enough in that glimpse of something you get at the start of chapter one to go on to read the rest, but the audience doesn't know these characters enough to care yet. I understand why it was structured that way, but it doesn't quite work.
All of this is just my personal opinion as a reader. As a writer, I understand why you wrote it this way, but just keep in mind that a person who knows nothing about the world and characters you created needs a reason to care. That's what makes them go on to the rest of the story. Your writing is good, and I think there's a lot of promise in the story!
