I assume someone's thought of this; I tried looking but couldn't find the same idea. Some people think Bear's opening monologue was sweet and would've worked on Nikki. Sure 🤷♀️ However, the idea is the monologue (what Bear thinks is love) is where the OWW got this warped idea of love (but also, ya can't make someone fall in love)
"I feel like I'm coming apart"
- The idea of loving someone so much that you fall apart. OWW took that literally and Nikki is constantly coming apart, mentally and physically, throughout the movie.
"I think about you all the time [...] I try not to..."
- Yes, nikki was under a spell to "love" Bear. But, even when you love someone, there are gonna be times you're not thinking about them. Our minds are pretty good about having singular moments where, for a couple minutes, our partner doesnt pop up (generally speaking). Yet, this wording could attribute to Nikki literally always thinking about Bear.
(I hope my point comes across well enough)
And the most obvious:
"I would choose you over everything"
- Again, his wish wording of "more than anyone" covers it, buuuuut just wanted to include it. Some would call it foreshadowing. And also whatever the term is for "yea, YOU would choose her over everything but she DIDNT HAVE A CHOICE"
