Zorobin: sign of hidden love?
While the Straw Hat are traveling to the Island of Fish Men, there are several scenes where Zoro and Robin are together.
Not to mention - if you are careful - you can see that in the meeting after two years Zoro personally went to see Robin.
Well: during the trip to the Fish Island, there is a very significant moment. Zoro, along with Rufy and Sanji, goes deep into the sea to face the gigantic Kraken, a dangerous undertaking, as they may die drowned.
Nami, obviously, you can see that she is worried about Rufy. And Robin? She does not like to show openly her feelings for Zoro, but these feeling are presents. Look closely at Robin’s right hand: she has her pinkie finger raised. A somewhat odd position, right?
The point is that in Japan that gesture has a definite meaning: it means having a relationship with someone. Luffy? Of course not, because he is with Nami. Sanji? There are no special relationships between Sanji and Robin. By way of exclusion, Robin’s gesture is only directed at Zoro.
And why is she doing this? I guess for good wishes: besides, Zoro, before leaving, he could has glanced at Robin, right? And she could not greet him openly, it would have been too explicit, so Robin wanted to give Zoro a very clear and hidden message, as it is in her nature. Finally, it is as if she had told him “I love you”.
