Heart like a wild horse

My heart is a wild horse, you tie the reins on it.

Why do you walk fast and slow? I'm worried about your eyes.

My heart is a wild horse. You nail it with a horseshoe.

The water in the front mountain has been razed to the ground, and the iron shoes you gave me can't be broken.

My heart is a wild horse. You saddle it.

I don't feel any burden, just remember your hug.
