The people don't want to go back to being part of Ukraine and there is no scenario where that territory will be part of Ukraine again.
Deal with that reality.
And I am also to believe that Kherson and Zaporizhzhia with 80% Ukrainian populations also voted overwhelmingly to join Russia. The absurdity of such a claim discredits all referenda. But Russia and its apologists got their talking points, and that is all that matters, right?
