The Mark of Zorro

I read "The Mark of Zorro".

I haven't seen the film of "The Mark of Zorro" ever. I knew the story of "The Mask of Zorro".

After I read this book, I have a question for Zoro. Zoro is Don Diego Vega.
Don Diego want to marry Lolita but he didn't know how to say sweet things to a woman. He can't to hold woman's hand, and play a guitar under her window.

Although Zorro knew how to say sweet things to a woman so Lolita falled in love with Zorro.

I wonder if Don Diego know how to say sweet things to a woman in fact, or not. Maybe Don Diego change his character when he tie mask.

If Don Diego know how to say sweet things to a woman, he should have say Lolita sweet things. If he did this, Lolita would love Don Dieg from begining.
