I'm not sure on what your asking, but if your question is why Nagi is rushing to finish her manuscript? then its because she has under a week to finish the master copy of her manuscript for a 25 page doujinshi. Additionally, she also has to make a front and back cover for the book, edit it, and have many copies made in time for her competition against Ruka.
However, if your question is if she has to start over on her manuscript after she had spilled ink on her pages? then its a possibility, but this image from Heaven is a Place on Earth. could also imply that the ink "might have" been removed from the ruined pages and are hanging on a clothes line to dry that or Chiharu put the redrawn pages up there to prevent any further accidents.
