I just got the first two volumes of Didn't I Say to Make My Abilities Average in the Next Life?! and I finished both in less than two days. I just could not put the book down, one moment A is happening but almost as soon as A happened we get B, and we just have to see what happens and then C happens almost right away; There is absolutely no fluff or unimportant content in this series. This series does not have long periods of nothingness like many other series have. I had to force myself to put this series down and other series such as Shield Hero, Konosuba, Vending Machine, Smartphone etc. because I just would not stop reading it until I finished the book. Even the fights have so much content in them where something like Accel World drags out almost every fight to the point where we just want it to stop, We get it, the game is supposed to be a game, its supposed to be fun not ruined by some guy. I also just noticed that most of the series I just can not put down were originally WN, so they typically would have short chapters and each chapter needed something to happen or change and be interesting, so where some LN will take 2-5 times longer to get to the important points or have something happen, a WN needs to keep the readers hooked wanting more and tuning in next week or month for a new chapter, so they make something happen, they change something, they introduce something, they conclude something, they add to something, they progress something, they do not add fluff (unless it is something like Chinese WN where they get paid by word-count).
