Bering & Wells: screenshots from ..3..2..1
In the shipping's defense, I think Kuvira's love for him was genuine. She clearly looked distraught when she fired, she didn't treat it as a casual thing. She simply decided that her goals were more important than him, I think the shipping is only destroyed in canon after she fires because, after that, it's clear that Bataar Jr doesn't love her anymore and deliberately gives the others information on how to take down her machine. He did genuinely love her but he felt betrayed afterwards.
