This is arguably one of the best yuri fluff works you could ever read. This fluffiness creates a tingling, bubbling sensation somewhere in your heart. And it's not boring or repetitive by any stretch.
I could call it a series of one-shots set in a shared universe, but basically, the entire first volume is a set of several stories segueing into the next one. They all are about happy yuri marriages, obviously set in an alternative Japan where same-sex marriages are legal. The second volume continues the storylines that started in the first one and adds a few new characters.
The timeline is a little messed up, though, but if you don't care about minor details, it shouldn't bother you. As I was reading this, a silly and happy smile almost never left my face. So, if you enjoy yuri fluff, don't miss out on this one. It's a true gem.
