The Youngest Prince Has Left TYPHL

Ciel hated boredom, so his pursuit in life was to find interesting things.
When he died, he died. It wasn’t painful anyway.
When he woke up, he found himself in the novel ‘The First Saintess’ as the main character’s obsessive stalker. The only good thing was that he was still a child.
Ciel, who had become five feet shorter, contemplated life and came to a solution.
“Stalking someone’s not interesting at all. Should I just leave?”

Warnings:
There is probably going to be no romance. ¯\_(ツ)_/¯
There might be LGBTQ+ side couples.
Some characters including MC are pretty androgynous.
