This is an AU and things are a little different... Ace ain't dead for starters. Sanji grew up the same way he did in canon but when he went to WCI his brothers started to feel emotion again, they were terribly sorry and apologized profusely, and of course Sanji understood, they were all under Judge's control and didn't have free will over their emotions. Another big difference is that Sanji was the perfect person in everyone's eyes, charming, handsome, smart, thoughtful, compassionate, kind, just perfect, and he wasn't a perv, he respected women too much, he still didn't fight them but he wasn't a simp which meant most girls fell for him (Not Nami or Robin cuz he's too young for Robin and Nami's just a single lesbian bad bitch) and he actually had a lot of admirers, most of which are guys. But Sanji was oblivious of all his simps, and he had 3 major ones, the most obvious of which was Zoro, the other two were a little unexpected though, they were Law and Ace.
