So far most of fiction I've read with this ship was about Palpatine seducing Anakin, Anakin having a strong dependance on him, some kind of Stockholm syndrome vibes, yadda yadda. And there are PWP and crackfics.
I want something else. Like the two of them loving each other deeply and caring for each other (in their twisted Sith-y way, of course). No abuse, no plans to kill each other, or other things like that.
As for the timeline, I'm not really picky, choose whichever you like. Though I admit I'd prefer the OT period.
