I believe he's considering it after the end of day 12, which he posts
here.
I have a copy of Decision of Life, but only to investigate the code, since it's easier to find things out that way than playing through it. I was initially curious if all the parent/child relationship were changed, as is the case. It could have been very telling if say Leah (Ava's daughter in the 2nd side job) was her daughter in DoL, but the sons were lodgers.
But no, with the exception of Ellie being Sophia's "friend" and Patricia being Sophia's "best friend" (which is the only real thing of interest I've found so far in DoL regarding incest) and not "lodger", all the other children of characters are "lodgers", and the mothers are "Landladies".
