If you re -watch that scene again, you will noticed that she started out being matured and accepting, that he…
I understand that some people might find it normal for her to slap him. But in the context of the story, I think the reaction is a bit excessive.
We're talking about a character who has always been respectful and considerate, and the scene mainly depicts an impulsive moment fueled by jealousy, not someone trying to be violent or disrespectful.
They are clearly presented as having feelings for each other, so the fact that she suddenly looks at him as if he's a horrible person seems a bit disconnected from the dynamic they had up to that point.
I'm not saying what he did was perfect, but the scene feels like a somewhat forced dramatic twist, mainly to create conflict. In my opinion, it wasn't really necessary for the story.
