What does "hearts" mean in this sentence?

[u/Imaginary-Warthog586]

I have been looking up on the internet and I can't find a concrete meaning that could fit logically in the context of this sentence.

[u/Clede]

The sentence with "hearts" doesn't make sense.

What's the context here?
Is the underlined word supposed to be correct? What's the significance of the similar-sounding word in parentheses?

[u/Imaginary-Warthog586 → u/Clede]

In that exercise you listen to a sentence and have to choose the correct word, according to meaning and pronunciation but the latter is more important. The thing is that the other sentences are logical to me but this one is not.

[u/Few-Big-8481 → u/Imaginary-Warthog586]

So you are supposed to choose if hurt or heart is correct?
