Sorry but no way in hell is Zoro in love with any of them. Nami is to much like a sister, Tashigi reminds him to much of a dead friend and as for Vivi there really isn't anything to point to an attraction between the two. If anything I'd say he has more of a thing for Robin.

Yeah but Oda says that the straw hats can't date each other cause I remember that someone from the Anime Vice mentions that story .

Even though One piece is NOT A DATING series and has no romance whatsoever, I personally think Robin belongs with Zoro. First they respect each other. Tashigi only annoys Zoro, Nami is too over money, Vivi? I don't think they even had a relationship. Some people ship Zoro with Bonney and Perona but I don't think so.

Oh come on, Robin just doesn't really work with Zoro- only Nami really has sort of action with Zoro and they look so much better together. Their characteristics work so much better with each other - Dont understand why people ship Nami with Luffy and Robin with Zoro

tashigi is the same ditto of zoro's rival and love interest kuina.........and she have a soft spot for zoro as well.....they r the best match for each other...........

as for robin in my opinion is franky..not only that she is 9yrs older zoro.....he he he
she is best suited for franky.............he he he
