This really is one of the most enjoyable fanfics I've ever read. It's still in progress, but it updates fairly frequently. The writing style is amazing and hilarious, but the writer still manages to pull off angsty moments with a surprising degree of skill. There's a little bit of Fridge Logic
at times, but that's all part of the fun. The basic plot revolves around Arthur, Matthew and Lovino dumping their boyfriends and then forming an unlikely alliance to get revenge. And it is glorious.
