Have a decent time visiting them at the very least ^^ hopefully have a great time. And the two threads/timelines will only really be an issue if something significant happens in the restaurant thread. Just using it as an example, but if Hanako hacked into Sheila and had her go streaking or on a panty stealing spree from the crew later on in the restaurant after everyone was already rping with sheila as if everything was normal. Or one of your characters and someone else's had an intimate moment and finally came together as lovers, or had a huge fight and in the mission they were still being rped just like they would have been before it. So long as your characters don't do anything to out of the norm there would be no issues.
