Insta account private or public? To get followed back

Insta account private or public?

When as a guy, I am "follow" a lady I'm interested in, and I want her to follow back

Public would give more context to who I am, I do have some nice pictures etc

But private account would intrigue her curioustity to see who just followed her or requesting to follow her

What do you think has better probability for the lady to follow back?
