So, I don’t read this crap anymore, but I do read other manga published by Young Magazine, and I always check the site for the latest uploads. I noticed this manga hasn’t had any new chapters on the Young Magazine website for a while, and I was curious why. On the author’s X, she posted on July 18 saying she’s hospitalized. Looking for more information, I checked the translator’s Discord, and it seems the author mentioned somewhere that it’s a psychiatric problem; she has bipolar disorder.
Still no news from the author, a lot of japanese fans are commenting their worries for the author's well being on their twitter, and still complete silence since the July hospitilization post.
I don't think they died since when an author dies it is usually announced officially by the company.
