Love the idea, not the execution
The idea is great and I was really in love with the characters at first but then, the plot became very contradictory in my opinion. I don't mind the grammar mistakes but I'd suggest you either proofread the chapters before posting or use a program for that because it would make the reading flow a lot easier and more enjoyable. My main issue is with the storyline and its development:
Read the story now
Although I appreciate it being different from the usual romances and it gives it a realistic feel that they don't only focus on their relationship but have separate lives, it's a bit frustrating that the three don't spend more time together. They've been separated for years and now they rekindle and realize they are actually in love and instead of being in the honeymoon phase, they are constantly with friends and so on. I just don't get it, especially for this story since that makes it drag a bit instead of showing any progress in their relationship. At least that's how I see it and it also kind of annoys me how they act with Lu. She was introduced so suddenly and now she is like their bestie, hanging out at their place half naked and wanting to be close to all three of them. I don't get how she was so close to her bully (Bethany) and now she wants to be friends with Mari. I understand that the book isn't only focused on Mari but it strongly felt like it's about her building her self-esteem and her relationship with the boys but I don't think we've seen all that much of that. There was no progress to her confidence, she just got it out of nowhere.
It's also great that we get an insight on the guys' soft spots and all but I guess I am used to romances being more focused on the lead characters and this is a bit frustrating, especially with the constant change of POVs. You start in third point of view, then change it to their separate perspectives, then jump to third POV once again and then out of nowhere, we get the views of her brother, their father and so on, which seemingly has nothing to do with the main storyline.
There are also some contradictory ponts which take away from the value of the story. Like for example, we got the explanation that Isaac and Beth hated Mari because the boys only hung out with her but since they're back, they've spent most of their time either at school, practice or with friends so that doesn't really prove that. Of course, that's how real life works but I'd really like some development and seeing them actually spend time together and "be cute". I also truly hope they won't try and experiment with Lu in the future because that would defeat the whole point of their three-way relationship, in my opinion.
Also, something that bothers me is how every adult simply accepts the fact that the three of them are together without asking a single question. It just doesn't seem realistic in such a small town, as previously described.
I really like the plot and the characters but such stuff really bugs me so I wanted to share, please don't take it personal, it's just critique towards the story and the realism of it but I otherwise appreciate your craft and will keep reading your other stories!
