Spoiler answe:
Carcel found out that Ines regressed from the painter. The painter found out in the afterlife about suicide causing regression and dying an unfated death creates the opportunity for the Angel to grant wishes. Nevertheless, the key to Carcel finding out that previous lives exist happens after an assassination attempt is made on his life. From then on, Carcel learned more and more memories and eventually learns everything by the end of the story. He’s the only character in this story, besides the crown prince and Ines, who knows all timelines by the end of the story. In fact, he was given the entire knowledge of a timeline that hasn’t been revealed in the manhwa as yet. Not even Ines got that full memory.
Where have you been reading the novel ? I've tried to look for it and couldn't find it anywhere.
What did the crown prince do when he regained all of his timelines memories??
Spoiler
The crown prince already have memories of all timelines. That’s why he was able to groom Ines from a young age to move him. There is a hidden timeline that Ines doesn’t remember and the crown prince used his knowledge of that timeline to his advantage to win over Ines. In the hidden timeline, Ines didn’t like him and didn’t choose him. That hidden timeline is the “true’ first timeline
Correction of typo
That’s why crown prince was able to groom Ines from a young age to choose him and marry him.
That motherfucker
Novel readers, does ines tell carcel about her reincarnation(s)?
