This manga is about adult couple living in LA and dealing with their worries/problems with a bit of /y/ and parenting.

The manga is currently at 9th chapter and ongoing. It will probably be concluded in 1 volume, so 2-3 chapters left. New chapter is out on 10th and 30th a month. Read here: http://www.poco2.jp/comic/ssmarriage/

someone in 4chan is doing amateur translations of the first chapters: http://boards.4chan.org/u/thread/1923365/to-aru-kekkona-certain-marriage

That looks nice. I wonder if someone in /a/ will take try and typeset it.
