Flavio could see with the help of Miyuki all his life as Armando from birth until he died, the memories that Miyuki showed were what he had seen when Flavio shared the experiences of his life.
Only Miyuki changed them a little to show her why she had to leave him alone because a goddess cursed them after this Flavio had to see all the memories he had lived by the hand of death.
From the good times to those where he has committed some stupidities, all this allowed him to understand many things but it was something quite rare for Flavio.
Being able to see the two lives he has lived in the third person as a movie answers many questions of Flavio but left an existential void because for him it is like watching a movie where he is just an actor.
But he is willing to do what he can for his children, although he has some fear because he can be sure that Hellena will react in a completely unpredictable way.
