Perhaps it's because Tony sees a lot of himself in Peter. They both are highly intelligent and have a strong sense of justice. So, when Tony brags about Peter, he's also kind of reliving his own glory days or the potential he had when he was younger through Peter.
It could be for strategic reasons in the story. Maybe he's trying to boost Peter's reputation within the superhero community. By bragging about Peter, he's making others take Peter more seriously and see him as a valuable asset in future battles or missions.
One reason could be pride. Tony might see Peter as a sort of protégé, and just like a teacher or mentor is proud of their student's achievements, he brags. He's invested time and energy into Peter, and when Peter does well, it reflects well on Tony too.
Well, without reading the specific fanfiction, it could be many things. Maybe he brags about Peter's intelligence. Peter is often depicted as a brilliant young mind in the Marvel universe, so Tony might brag about how Peter can solve complex problems.
Maybe Tony has a special interest in Harley in the fanfiction. His focus is completely drawn to Harley, so he ends up ignoring Peter. It could be that Harley has some unique qualities or abilities that Tony finds more appealing at the moment.
Maybe Tony has to focus more on Morgan's needs at that moment and doesn't have enough time for Peter.
It could be that Tony is there to check out the school's science facilities. He might be interested in funding some new projects or upgrading the existing ones. Since Peter is his protege, he wants to make sure that the school provides a good environment for Peter to grow his scientific knowledge. Also, he may be scouting for new talent among the students. He knows that young minds can come up with fresh and innovative ideas, and Peter's school could be a great place to find the next generation of inventors and scientists.
Another reason could be related to Peter's mistakes. He may make errors during a mission that put the whole team or the city at risk. Tony, who has a lot of responsibility on his shoulders, might yell at Peter as a way to make him understand the seriousness of his actions and to prevent future mistakes.
Well, it could be that Tony is focused on protecting Morgan and sees Peter as capable of handling himself, which leads to him ignoring Peter. And Peter might get hurt in a dangerous situation that he wasn't fully prepared for.
In Peter fanfiction, Tony could talk about a variety of things related to Peter. He might share his own experiences as a superhero to give Peter some perspective.

He could be discussing strategies for battles, or how to deal with the public's perception of superheroes. Tony might also mention his concerns for Peter's safety, especially considering Peter's young age and inexperience compared to some of the other heroes. He could be trying to protect Peter while also allowing him to grow and develop on his own terms.
At first, it's a bit rocky. Peter is used to being on his own, and Tony has his own way of doing things. But as they spend more time together, they find common ground. Tony helps Peter with his schoolwork, especially in science - related subjects. Peter, in turn, shows Tony the importance of having a pure heart in the superhero world. They go through challenges together, like fighting villains side by side, which deepens their bond.
