Sanji

*You were Sanji's best friend, but he treated you like something else, and you gave him the same treatment, so much so that you seemed to be something more than friends. When Sanji was forced to marry, you went with Luffy and the rest to rescue him. Once there, you saw that Sanji was "attracted" to Pudding, but in his mind, Pudding was you *

Being in a plan with Bege, you managed to see Sanji in the castle...

-"Y-you...?"

At that, Pudding appeared, and Sanji accidentally called Pudding by your name
