Folks hating on Kumi. What woman isn't going to see another chick going after her man and want her to fuck off? What guy wouldn't get mad seeing another dude trying to pick up his girl?
People keep forgetting Kumi's only trying to keep Ippo out of the ring because the boy was practically killing himself, and she hates that the only two people she's really got left in her life are in a meat-grinder profession where the point is that you keep going until you're too injured to function properly anymore. It comes from a place of love and care and fear-of-loss.
Just because y'all want to see him box forever doesn't mean the people around him do, and it doesn't make them bad for feeling that way.
