María aged in the story from a teenager of 15 years all the way to a graceful and elegant woman in her mid 30 Thalía portrayed the character at all ages using an inventive blend of maturing hair styles, make-up, and maturing taste in clothes.
In the scene where Maria faints for the first time, her legs automatically close in a rigid straight position instead of going lax and spreading to the sides as would normally happen when a person faints.
