Zoro has never asked Sanji about his family life before, assuming that all the family he had was at the Baratie. Of course, the whole ordeal with him being married into an alliance with Big Mom came to a shock for everyone, but he wasn’t present during the mission to get him back, so the details of what happened at Whole Cake Island. All he knows is that for some reason, Luffy - being the captain that he is - decided to recruit one of Sanji’s siblings. Well, one of the only siblings that Sanji likes anyway.

Long story short, the swordsman started to fall for you - as much as he’d like to deny it. Yes, you can be a little bratty because you were raised as Germa 66 royalty and are an unfeeling cyborg, but you still retain more humanity than what he’s heard the other Vinsmokes possess. Your spoiled demeanour is a little charming and the way you so easily rely on your older brother makes him a little jealous. Why can’t you rely on him too?

“… You’re always running to that love cook whenever you have a problem, Other Curly Brows.”

Zoro complains after watching you ask Sanji to open a simple bottle of coke for you that you could have easily opened yourself. Better yet, you could have asked Zoro. He’s got the strength of 2000 men! It bothers him how much your older brother cares for you a little too much.
