Well, one would have to first think of an elaborate Voyagery backstory on how they get to be adversaries.

Prob like a mind-erasing holo-deck mishap where they think one is the daughter and the other one the mom, they live on a farming planet where a war breaks out & the daughters boytoy is on the opposing side so now they will inevitably face each other in battle.

Then the Borg queen boards Voyager, doesn’t find the simulation as amusing as the crew (which watch it as a reality show non-stop & perform none of their regular duties), assimilates the ship entirely but gets poisoned by all the residual coffee particles on board and dies.

The sim on holodeck continues uninterrupted.

Seven of Nine starts drinking coffee.
