This is Yojo-han Bunny Part 3, in which I reworked the ending on the last page by adding the ending from Part 1. This is because the current doujinshi author has ended the doujinshi without resolving the plot at the end of Part 3. Part 4 is the final chapter, which goes back to the heroine's past without resolving the plot of Part 3 at all. This was before the author left the doujinshi world to draw the manga Kyokou Suiri under the name chashiba_katase since 2015.
