@Introvert So
Spoiler!
He was not in Trovancha during the first timeline so he was unable to save his sisters. He was only able to come back after Liliana died. After Lili died, Marius and Francois come back to their senses and wanted to make amends. Andrea made them do a soul oath so that there wont be a repeat of the first timeline. Included in the soul oath is being able to remember the past. Only the three of them should have remembered the past but Liliana also remembered them in fragments because she gained her powers because Andrea kept on turning back time during the terrorist incident.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule you will find me in most romantic historical manhwa comment sections
