so basically, duke castielo loved lippe in the past. (like before lippe traveled back in time and it was during the time where a tragedy happened to her family) the duke also traveled back in time to his age now, which is 8 i believe. currently, he is trying to save lippe’s family so they can live a happy life. the duke still likes her i think so thats why in the beginning he was acting like that. the duke also confesses to her somewhere in the book that he is from the past but i think lippe doesnt believe him? ( i think he also confesses his feelings) i think that he also plans to get engaged to her too, and her family doesnt really want her to get engaged, but they reluctantly let them get engaged?
