Why should she?
This is what she wanted. Noru is standing up for her. She desperately wants this boy and always has for her whole flippin' life. She's looked after him because he was quiet and meek.
Now he's putting himself on the spot and busting out some effort to show her how much he cares. Even if he loses, so what? She can just tell the other guy to go suck his own dick and take Noru home all the same - because just the fact he's doing this for her is already dreams comin' true.
You're thinking about the unfortunate rash of people we have in the real world nowadays who'd try to get you arrested just for opening the door for them. I don't even consider those women, just people trying to find something to be angry about.
