Its kinda like a regression after the reincarnation (am I right?). So in the first life is the novel yenseo have read in earth (2nd life I think) then from the 2nd life, he regressed into his first life and like living his 3rd current life? I'd love the idea where the three of them became real brother and sister that his older brother is prince cedric and his younger sister is christelle
but if he is the only outsider, could it be a parallel world or smth? since he in the modern world had his sister and brother while in the novel world, he had also the two characters with a close relationship to him like a brother and a sister?
