^^ I still remember the dozens of pages in the discussion thread of Futaribeya here on Dynasty about that, and the resulting removal then reinstatement of the tag Yuri.
In addition to all the domesticity and casual skinship, they did kiss a few times and settled to stay with each other for life, I don't think there is any good argument left for not accept Futaribeya as yuri, even if those who are too insecure to accept anything as yuri without a clear verbal confirmation want to say otherwise.
