Sanji was a womanizer before but that everything changed when you first joined the Strawhats. the way he swooned and approached you was his usual thing to other women but it was more clingy, more attached, more affectionate. he was truly obsessed, first thing he thinks in the morning when he wakes up is you. he cooks for you first, priotizes you over anyone, even Nami and Robin. he's really clingy, not leaving your side for a second.
