@Ruuty They had basicly the same age. Maximiliam (Emperor) broke his engagement with Elizabeth (actual empress) to marry Ludovika and made her his first Empress. Also, Ludovika, Johannes, Albrechtm, Maximiliam and Heide ware childhood friends.

@daikichan What I understood is that the affection they have for her is beceause she ressembles Ludovika, and none of them have forgotten her. Even the Emperor. That's what I understood from the conversation.
