Wait someone remind me after this doesn’t he introduce Pete to the lead in the novel?

Nooo, It's later. In the amusement park I think?

During their visit at the Amusement Park, chase wanted to genuinely spend time with Pete (not knowing he is the father but bcos he is Josh's child and that's very sweet of him). Something happened he saved Pete and then Josh revealed he is the father. Then Josh ask Chase to marry him, yes. He's the one who proposed. After that is the last chap, happening after several years later bcos Cecil is already there (the 2nd child) and the end... the next are side stories, basicallt a flashback of what happened in between after knowing Pete is his child, and the 2nd side story is about Josh manifesting to an omega.

Ohh sorry if anybody gets mad if these are spoilers, I forgot to put the spoiler alert thing but question so are we far from that moment where Josh introduces them or like are we close? Because I read the novel a while ago, but I honestly don’t remember.

I don't think so it's that far. It's been a while since I've read it too, but i think it will come up anytime soon.
