END OF STORY spoiler below
First, you’re wrong on him not going home. He gets with the captain cause hint hint something connects her with his own world. Second, he goes back to his old world because he kills or destroys the co author by sacrificing himself (he goes alone without anyone) then after the word reverts and everyone’s memory of him is faded
Actually that’s for the best. He misses his family, but he wouldn’t want the connections he made in this world to suffer without him when he goes back, yet he wouldn’t want to stay (I wouldn’t want to either if I have my family back in my og world) so it’s best for them to forget him. I like that kind of ending.
He's gonna end up with the captain?! He's not gonna go back to his own world?! Bro the author really plans to fuck the MC's life. I still wonder maybe he died and just doesn't remember that's why he's on his own novel that is being rewritten by someone else.
