Review Detail of ShadowYuki in One Piece: Wild Hunt

Lets say you have a crush and she promises to go on a date with you after you get A grades in your semester but the very next day she slept with her teacher and then blatantly shoves it to your face , then i consider it to be an n.tr, that what exactly happens with the MC of this novel. Drake promises to be with him(MC) after he grows stronger but few chapters later drake slept with MC's teacher Chiron and shoves it in his face. Now the author will argued about this is lots of the comment but u need to understand that Drake is his captain of the ship which the MC cannot avoid or forget even if he wants to. Also if we want that much realism and drama in your novel would we not have read a proper novel instead of a no name author's fanfic??
