Seems like there are some untranslated stuff - pretty bad quality though - on the artist's blog, unfortunately it's unclear whether he's still continuing this or not given the last blog post related to this was from 2019 and there hasn't been any update about it over a year. I really, really hope the artist isn't done with the series, it's pretty hard to find a gem like this.

Also, can anyone recommend more manga like this where the couple is affectionate with each other?
