It can't be *that* similar to Jahy-sama if there's a man involved.
I read the one-shot & while its not fully Jahy-sama, the premise is somewhat similar.
Edit: I read till the latest translated chapter, which is 9, but technically 14 chapters if you count the Omakes, as of now, it's fairly fun & cute. There is a massive scanlation consistency issues, many such cases, but goddamn it's always sad.
The translation has been going since 1st July of 2021, it was done by a scanlation group called SVQ Scans. They had a fairly consistent schedule till 30th January of 2022 when the translated 8th chapter was released, then they just stopped.
Chapter 8.5, the Omake for CH.8, was translated by a user name starg09 who translated it from a DeepL base, the came out on June 13th. This manga was weekly, until it went bi-weekly due to mangaka running out of ideas (he admits this on the first Omake chapter), but as per starg09, it gets a chapter every other week with a 3 page Omake on the off-weeks. As of 13th June 2022, there's been 43 chapters released with a 3 page omake for most chapters. It's been a month since than so I won't be surprised if there's around 50 chapters, or more, counting the Omakes.
The last chapter & it's omake came out 4 days ago from now, by a different guy named kristopoh. As per him, the redraws are easy for him to do, but he's a beginner so translation takes a lot of time, so it might take an estimated 2 weeks for him per chapter.
TL;DR: No wonder it got an animation, it seems to be a fairly well doing manga on Jump Plus. It seems to be a fun manga which is the closest thing you can find to Jahy-sama type manga. But if anyone wants to read it & be up-to-date, it's impossible unless you know Japanese & find the raws.
