Non-PRO English to Croatian Other Linguistics One\'s characteristic or a trait, something he, she, or it is known for

I am interested in Croatian translation of the phrase "wild at heart" in the context of a city/town:

Here are two possible explanations (unfortunately, the following primarily refers to humans):

"I think it has two meanings, One if you have a wild heart your untamed and tend to get bored with your partner so you often cheat. Two if your wild at heart you live on the edge, you crave that adrenaline that gets that wild heart pumping."

"It means you love unconditionally, freely, passionately, wildly, blindly, without restraints, just like a wild horse that has escaped from a captor, and is running through a sunny meadow, full of fragrant flowers, looking forward, running toward your safe haven, and never even thinking about looking back to what you've left in the dust!"

THANK YOU!
