This review is a bit late due to Kindle app and PTSD issues. (That's a weird sentence, I know.) 
 I really appreciated this book for many reasons, although at first I thought it was a bit boring and stressful, though it was also funny and cozy in the beginning as well. 
 I was rooting for them, though, and really wanted them to get together already! I also soon had headcanons. 
 It was mainly me feeling the stress of the characters, or the stress I'd have felt in their situation. It got better. 
 It helped me escape from my life and past a little bit. I liked seeing a character with secrets like mine, anxieties I also have and had, but in a "better world" than mine (or rather, it went better for them, I imagine them inhabiting the same world as me.) I liked that things went well. 
 At first, in the very beginning, I would have preferred if the secondary characters had been more developed, I regretted that they weren't more present, but then when going more into the book it felt better this way. It felt more like I was with Kyle and Stella, who were spending all their time together, always thinking about each others; thus, the absence of the secondary characters was normal and helped to make the book more cozy. 
 Because I really felt this book was cozy. And comfortable. Without pretending that bad things don't exist. 
 It's just, there are these characters, and you know bad things exist, and could happen to them. They also know. Some characters mention that the bad things happen, exist, but that they aren't like that and the main characters can trust them. 
 I liked seeing their relationship evolving, in a way that felt natural. It felt as in real life, things evolve without you noticing, and then you look back and wonder how you got this far. 
 I liked seeing them evolve as well. I liked seeing them getting over issues, getting past them, dealing with them and how it all gets better. It was refreshing. It gave me hope for my own life and is a bit like a healing balm on somewhere you've been hurt. 
 They felt really realistic. I liked seeing mostly healthy family relationships that I did not get to have, and I liked seeing the character being able to get support when sharing their secret. 
 I'm repeating myself. I guess mostly I loved that it 1. was a happy book 2. but didn't pretend things were happy all the time and you don't need to worry at all and you're very ridiculous to worry. 
 For a moment I felt really comfy and like IRL problems didn't matter, and I felt a little bit more safe. I guess having had many things happen to me my brain thinks things are going to be bad all the time, and I feel a bit better thanks to books like this one, it's like it's retraining my brain, giving it more examples of good situations to add to its patterns of life situations library. 
 Like, this book contributed to making me noticeably less stressed. 
 That's enough because I don't want to spoil it by trying to give away more details. There are a lot of passages I highlighted that were heartwarming, but I prefer not to share quotes as it will not have the same effect on people out of context. 
 Tl;dr: I was really into this book. I loved being with the characters. The cute little things they did sometimes. Watching them evolve. The feel-goodness of the book. Thanks for the book.
