This book is a compilation of chapters that talk about the stories of the characters of the Classmates series after Sajou and Kusakabe's marriage. Since it is individual stories you can read any chapter you want and you will enjoy it still, most stories are about Sajou and Kusakabe living together or doing stuff as a married couple. But some stories touch topics that are brought from other parts of the series. My favorite chapter is definitely "Ice cream", a chapter that talks about Sajou's friend accepting the fact that Sajou never had eyes for her and it never will since he's a gay man, even if everyone that already read the manga knows that is obvious, seeing this perspective is very near, intimate and even sad but with a sweet conclusion that shows how this character moves from her romantic feelings that she has to let go. This type of intimate storytelling defines all the the book and is such a great reading for everyone not only for the people who want to know what happens after blanc but also for people who like close and heart-warming stories about family, romantic partners and friends
