Just for the Summer

The book's plot summary hooked me - the pair meet via a Reddit "Am I The Asshole" thread, and it turns out to they are both similarly cursed with having their exes immediately found "the one" right after their breakup. As well as the romance itself, there's a side plot surrounding some mental health issues and unresolved drama with their family. I think what makes a good romance for me is the buildup and the "pining" stage but it's mostly skips that and instead the main complication is the character's childhood trauma and issues with forming relationships with other people which is kinda meh to read about (sorry).
