Hi, I'm lookig for an ao3 fic, I remember that Phil says in a liveshow, that he is moving out with Susan(?) And in the end, he makes a video about moving into a house with a garden and he and Dan lying on a bed and susan was a dog and it was a joke.
Rise Again (ao3) - After the events of Phoenix Down, the boys are home and they’ve just gotten together. Phil is still healing from his injuries, but that’s not stopping the relationship from getting more and more physical as they explore this new side of them. And then of course, there’s the issue of coming out…
The dog is called Sarah, but I think this is the one you’re looking for ^^
