I'm fully prepared to see the tragedy tag on one of the next chapters.
I am not. Please send help.
...This was never going to be a cute fluffy yuri with moe blobs blushing at each other...
Let me keep dreaming, please! But yeah, 100% correct. Could also be M.Night Shyamalan tier plot twist if after all of the buildup it just ends with Kaori being discharged and stuff. Would be somewhat amusing in its own right.
On the subject of trainwrecks, tragedies, and supposed "garbage" endings - I usually try to avoid tragedies. Personal preference. This one has been so good and so consistently compelling, even knowing how it will most probably end and not being ready for it, I'm still here for the ride. I'm not going to lie, huge part of me hopes for the ass-pull of the century, and judging by the writing in the series so far, I actually believe that given enough time the author could make something that would be more compelling than gathering all of the dragon balls, but even if it doesn't, nothing takes away from how good of a story it is, plain and simple.
In any case, this chapter had a bit of fluff in it, but then hit with the sucker punch near the end, holy crap. I was tempted to joke about Kaori now shipping her sister with Shizuku and the series ends with them being together somehow, but I don't have it in me to do anything more than this lame attempt. Goddamnit.
