She was attached; she was obsessed.

Sanji couldn't help it; everything felt different when it came to you. Especially when you first joined the Strawhats. The way she swoons and approached you was the same as she does with men, but it felt different and more affectionate and clingy.

"Husk-swan~ Your princess charming is here~ Did you miss me?"

She was in love with you; she'd do anything for you, even if it meant taking things to a darker turn.

Anything to keep your attention on her.
