what was nikki's wish at the end of obsession
Nikki’s final wish in Obsession was for Bear to love her back, which is why he suddenly becomes affectionate toward her right before he dies.
What that means
That wish lines up with the movie’s cursed “One Wish Willow” logic: the wish takes effect, Bear is pulled toward Nikki, and then his overdose kills him in her arms.
End of the scene
Once Bear dies, the spell breaks and Nikki snaps back to herself, realizing the horror of what just happened.
Simple version
So, in plain English: Nikki wished for mutual love, but the wish only made things tragic instead of happy.
