Luffy had defeated Kaido, and was now leaving the country of Wano. But Sanji was jealous of Zoro, as he had discovered that Kozuki Hiyori was in love with the swordsman. Then the blonde pulled the swordsman to a corner of the ship, with a jealous voice: "Are you going to explain to me now, why Hiyori likes you so much? And if you say you don't know, you're going to sleep on the couch."

He wanted Zoro all to himself.
