Hi, everyone! Thought I'd give an update here rather than wait for the next week to give out a TL/N.
We're currently on Chapter 21, and we're expecting around 6 to 20 more chapters until the finale. The author has
announced on Twitter (along with their birthday) that the series will end "summer or autumn (maybe winter)". Because of the bi-weekly schedule of this manga, this means late June (6 chapters; start of summer, 13 weeks until) or late September (13 chapters; start of fall, 26 weeks until). My prediction skills are telling me we'll have around 13 or 14 chapters left.
Under some very big "maybe"s, we could be looking at a finale at late December (19 chapters; start of winter, 39 weeks until) or around this time next year (26 chapters; end of winter, 52 weeks until), but I wouldn't count on it that much.
No goodbyes yet; I'll be seeing this series until its end. Next chapter comes out on April 1!
