Read the dialogue closely when he starts talking to her.
He starts the section with this.
"Honestly, you remind me of that girl. It all started because of that girl. She made me have the desire to become even stronger."
*story gets told*
Now we are in the current moment.
"Honestly, you remind me of that noble girl, she had short blond hair and was cute when she was little."
If he just said the later out of the blue with no context, the person hearing it would have no idea what the fuck he is talking about. It is very obviously being implied that he dumped his life story on this very same girl a second time.
That or the author is just dogshit in general and accidentally had the MC sound like a retard comparing the girl to an idea of one she has no concept of. Imagine if someone walked up to you on the street and said "you remind me of that poster with the lack of inability to read I talked with a long time ago." That's not how people talk. I for one, am going to at least give the author the benefit of the doubt of just being lazy as opposed to stupid.
