Wait, it’s not chapter 3, but part 3, what happened?
Calm down, this release is the one you expected. Apparently the length of each chapter in Kira-kira Kaoru can be greatly different. Some chapters only has 20-30 pages while some others can have hundreds of pages.
Therefore I changed the release system. One volume will be divided into 7 parts, each has around 30 pages, regardless the chapter.
