isnt this stockholm syndrome? thus us totally stickholm syndrome right?

No, she was confidently willing from the start.

Just like Belle (Who doesn't have Stockholm syndrome, any other person who studied this illness know its) and the girl from Sachiiro no one room (manga)
They were full on dedicated and willing to take the condition sanely.

And sure enough, both of them fell inlove with the men when Belle and the girl communicated with their partner, and took the time to understand the so called "captors" that the cops and GASTON :D allegedly refer to as.

She didn't fal in love with him or become dependent on him.
