Kind of got obsessed with this work and decided to MTL it through Google Lens. The gist of the story I think is the girl boxer who challenges the guy (who's a world champion boxer) plays mind games by insulting his fiance which causes him to lose focus and throw wild punches. She dodges these while he gets tired and continues to inflict damage while berating him and his fiance all the while. By the end she tells him he lost because of her feelings for his fiance before knocking him out, then tells the fiance she can find a better man because the one she just beat is weak. So I imagine that couple breaks up and the girl boxer gets a sadistic kick out of it. Also love the art 10/10
