Hello! Just read your first two chapters, loved the setting of a magic school and that the story is being told from a teacher's POV. It was also nice to have the juxtaposition of elegant opulence and a seedy sort of underside to the setting in the first chapter, although I felt like there were some phrases and words that got a bit too much use in the first chapter--vile, pompous, poor lamb, etc. The metaphor of the sacrificial lamb being chased by the wolves is interesting, but because it went on for the entirety of the chapter it sort of obscured what was going on, so it was a bit confusing. Some of the wording was also a bit repetitive, like the line about "crimson of their falling drops of carmine liquid jewels."
The chapter was still exciting, and there's a sense of urgency to it as we follow the chase. There was also a lot of intrigue built up as to what's going on and how these characters know each other. Because the opening chapter was so interesting, it was a bit jarring to then switch to a more sedate pace with the next chapter, though I still found it interesting. You have some cool concepts, like the cat turning into the shadow and the bits of magic you show in the second chapter. The characters we spend the most time with are interesting, though it does feel like there's a few too many characters introduced in the second chapter and I honestly just remember Mine, Lydia, and Addai.
As far as technical bits, the dialogue punctuation is off. Dialogue ends in a comma when followed by speech tags (he said, she asked, etc.) and a period when followed by an action tag (he smiled, she stood, etc.). In the latter, the first word of the sentence following the dialogue should be capitalized. The other thing I noticed is some odd word choice and phrasing, like in the second chapter:
"YO! Be careful!!!" the boy avoided the worst with a spell.
It took me a moment to realize what was going on because the story doesn't tell us what spell is used and in what way. It's just that kind of thing, with wording needing to be a bit clearer so readers can better grasp what's going on. The word choices sometimes made me pause, like when the meeting is described as charming and heart-warming.
The quick change in attitude Addai went through threw me off and it took me a second to realize it was him. It's interesting, because now I'm curious to know why he changed so quickly, but felt like it came out of nowhere until I remembered it being mentioned earlier that he gave Mine an odd look when they were introduced. I do find it funny that he was initially said to be a true gentleman, lol. There are bits where we're told a lot about characters where it would be nice to be shown these things, but it's not really a big issue, just thought I'd mention it as something to keep in mind when introducing characters. I do like how Mine and Lydia were presented, it was a fun way to show who they are as characters with the different way they responded to being late. Lydia sounds like a fun character, btw.
Overall, I think your story is fun, your characters are different and interesting, and there's enough of a mystery being built up to keep readers asking questions. It's really a matter of editing a bit and making sure your wording is clear in how you paint a picture for readers. The pacing is good as well and the bits of worldbuilding you do make the world of your story seem interesting. Also, not related to your writing but your art is very pretty! Love the soft sort of vibe your style gives off, very charming!
