So who was Pauline singing about/for at the end of odyssey?

The song was supposed to be about mario and peach but they didnt even get together in that ending and now its confirmed they are forever friends. Was that song secretly about pauline and mario being married and going on a honeymoon?

maybe that pauline schizo is right
