Launched in Space (A Ludwig von Koopa x Rosalina Story)

This takes place during the events of "Super Mario World", but I'm changing a fate here.
Today had been a very bad day for eldest koopaling and one of Bowser's minions Ludwig von Koopa. When Mario rescued yet another Yoshi egg; he launches the fortress with the eldest koopaling still inside to outer space. After landing on some unknown place, Ludwig exits the fortress bruised, cut, battered and to his dismay miles and miles away from home. Even worse; Ludwig found out he's no longer on Earth, but he found himself on a different planet completely lost. The frightened koopaling's heart softens little by little when he meets the princess of the galaxy Princess Rosalina, and friendship starts to develop slowly. Is this more than friendship though?
