The direction of this fic

[AN: While the plot has yet to be set in stone, I figured I should get input on how this fic would go. Just to be clear, this input is purely out of curiosity because by the time I come back to this fic some new knowledge from the Canon might affect the plot of this fic.

Should this fic be:

-No Romance, lone wolf and ruthless but has a code type of MC. (Ngl, this is what I am gunning for in this fic else it would resemble one of the other One Piece fics I have.)

-Some Romance, one love interest, ruthless.

-Give me some ideas.

-Ruthless, no moral and Aizen level of manipulative type of MC.]
