It's not NTR if she doesn't actually break up with Baki and hook up with Ali Jr.
Seriously, I pity some of the commenters on this site. Are you so ignorant of basic human compassion and decency that you just don't consider the idea of showing basic kindness to someone who's suffering?
Him and Baki simply lived in different worlds. You can't say he did anything wrong it was just that Baki had more crucial experience than Junior. Junior has my utmost respect as a fighter but he once again simply has so much more to learn in the world of grappling.
