One of the best fanfiction in the DD universe, the author really gave it his best. I don't think i'll read it again but these 200+ chapters were good and to the point. He tried to make things logical, with good use of time skips the romance is there it's an OTP so i gave it bonus points. The MC himself is hard working and he has a set goal. He puts thoughts into his actions without pretending to be a mastermind behind the scenes too much.
It's definitly worth reading !
