This was such a great read! I wished it were longer - but kind of not, because my eyeballs couldn't have withstood leaking any more than they already were, but since some things were more summarized nearing the end, I didn't feel quite completely satisfied with some aspects of the story. Thankfully, those were minor aspects involving minor characters, so it wasn't too big of a deal.
Anyway, I loved Ollie and Sebastian. This is one of the few instances I found the insta believable, because it wasn't insta-lust but insta-like and we've all been through that, whether romantic or platonic. They actually go on dates, and get to know each other, and the relationship is built up believably enough that when things take a sudden turn for the worse, I actually found the emotions and struggles to be realistic. I also liked Ollie's brother Tyler, even though he constantly abused "init" and acted like a typical moody teen at times, but he really showed how much he cared for and adored his unorthodox big bro.
Plus, Sebastian is bisexual. He said it. He explains the internal biphobia, the problems he faces when datings straight women or gay men. I am so, so glad that more authors are embracing bisexual characters in their books and getting away from the GFY trope.
I do wish we'd gotten to see more of Sebastian's family - even his uncle cuz I want to take that moment at the dining table and frame it on my wall - you'll know that moment if you read the book. And there was this other thing between the besties that happens at the end too, that I'm not sure why it was included at all unless perhaps Ms. Haken is thinking of a potential sequel, which I would definitely read if so.
