romantic???.... let's remember the times that luffy saves any girl either in a social, physical and psychological way... then he would already have a harem... of course if oda didn't say that "they are in love with adventure" ... how will rob react if oliva tells him that she wants luffy to be her son-in-law for saving robin???... after all, he declared war on the world government for her and told her to live.... the girls: how romantic!!!!
