I had been reading this one and dropped it a while back (read up to chapter 90 according to Tachiyomi). It didn't feel anywhere close to the end, so I am surprised to see it ending so soon. It doesn't surprise me that the ending felt rushed. I will have to just dive through the rest to the end since it is done.

EDIT: Finished this up the other day and collected my thoughts over in the fortnightly thread.
