It is obvious Chouji and Karui are her parents, even Naruto noticed that. She just does not want to admit it cause she thinks her father is not cool enough :D While mystery around Sarada's birth are interesting (though I think we will get a pretty normal explanations), Chouchou "journey" is there just for comedic purpose.
