I'm reading Misfortune right now and I really like it! I don't know anything about these characters but you quickly established what each relationship dynamic was like and I know a lot about Peri from the way he talks to others- your characterization is excellent!! I'm really interested, and especially loved the scene with him and Rowen!
I think the first chapter could've used more variation in sentence structure; every now and then you used the same length sentence a couple times over and the paragraphs didn't seem to flow as well, I guess? It isn't a huge issue and the actual content is great! I just got a little stuck, especially near the end of the chapter where I think you used a sentence split with a comma three times in a row and it felt repetitive.
Another thing I noticed was in the scene with Levi, you really got the sense of chaos across well, and I loved the dialogue in the scene. Maybe consider changing the tense with some of the action as well- instead of "He laughed and rubbed the back of his head", maybe "He laughed, rubbing the back of his head"? I don't know how easy it is to switch tense, but something to consider!
I'm excited to read the others- I'm a huge fan of the characters already! Do they have a visual reference?
