Thanks for posting that!
What is the last volume? 8? Wait- So, she may continue but the artwork might change due to her condition, right? Or someone will be her substitute and draw for her? Wahh I hope she'll recover soon and spend her time with her friends once. I keep praying that there's a chance that those two main character to level up their affection~(⌒▽⌒)
But the other reader's question was still remain unanswered. They expecting that the latest volume would explain the situation.
For those who keep asking and arguing about the story goes please read this and understand the situation of the author. Be thankful that she finished the vol 8 even the strength was left cannot draw.
It has to be so hard for her to not be able to draw the way she loves. I'm not sure if she will share duties with an artist or have someone else draw it all.

I did a bunch of research on this as it's one of my favorite manga's and here is what I found. Some people may not know this, but the author has health issues that have made it very difficult for her to continue. Volume 8 in English is due out in March 2018. From what I've seen online it seems that will be the final. She does go on to say she may continue the story in the future, but the artwork would have to be a bit different. Also volume 12 in Japan is our volume 7. Here is a translation of what the author, Odagiri Hotaru has to say. https://forgetful-amoeba.tumblr.com/post/161854523024/translation-of-afterword-by-odagiri-hotaru-in
