It is one thing for the mc to not be your favorite, but to hate the mc and still read the story is really weird, especially one where the story revolves solely around the mc.
Because I invested too much on this story.
Seriously, bro, if you grow up like me, watching pre Timeskip One piece's sad, dramatic, and emotional moment, PLUS listening to those pre Timeskip adventurous, bittersweet, Opening and Ending songs... You would love One Piece more than your first love.
And this is a huge emotional and time sacrifice and/or investment.
