I would like to bring up two works for translation consideration:
https://mangadex.org/title/62045/dairoku-sense
The protags are a 14-year-old boy and a early-30's(?) woman police detective. It's a supernatural-flavored buddy-cop crime mystery series that, to my eyes, seems there's the potential for (tsundere flavored) romance between the two leads. There's a group already working on it, but they are a principally Polish scanlation group and their English translation is done via JP > PL > ENG, which comes out as very stilted and frequently grammatically incorrect. My hope is that you can provide a cleaner, more neat translation.

This one seems to be more towards your wheelhouse. This looks to be a spiritual successor to Watashi no Shounen & it's first chapter plays out similarly. The protagonists are a 30-year-old Office Lady and a 16-year-old (seemingly) homeless high-school boy, the boy literally shows up one day on the doorstep of the lady's apartment. The Japanese name reads, from what I could manage, as Shounen o Kau & it has a provided English title of Sweet Days with a Boy. It started in Autumn of 2020 & It's first volume was released this past February. Nuwi Aoi is the author (her Twitter is here: https://twitter.com/nui_blue). There's no entry for this series on MangaDex or MangaUpdates, nor does Nuwi Aoi have an entry in MangaUpdates.
You have a great day.
