Im not sure what these 3 lines mean
Im trying to trabslate these lines into English but I dont think I understand the Korean

Original:
솔직히 말해서 너는 왜 그렇게 너무 아름다운 거야
함께 하는 동안 조금씩 들은 너와 나는 다를 거야
우리가 싸운 다음에는 가까워질 거야 더

Translation:
Honestly speaking, why are you so beautiful
You and I are different, you might get while we are together
We will be closer if we get over all of the trouble

Answer

Are these kind of lyric from a song? 
I am Korean but I can't get the meaning of the 2nd line.
I think there would be a missing word like 정 right before 들은.
As 정들은 means "get emotionally closer" , the sentence can be translated like this:
You and I would be different (from other couples) because we have been more and more intimate as being together.

Answer

To be honest, why are you so beautiful
You and I would be different, which can be heard as we being together.
We will gonna be closer after we fight each other
