Falling in love can be the theme. You can deduce from the story that no matter how bad things can get, there will always be someone that will be able to lift up your spirit again. You just have to be patient.
==>True to this case the speaker of the poem is falling in love to a woman after being hurt by the sounds of things.<span> </span>
If the sentence in question is a statement (ends with a period), I would probably "however" as your transition word.
<u>I would risk my life for my friends. </u>
<em>I agree with this statement, because I hold great value in my friend's lives. I could easily risk my own life for theirs in order to protect their well-being.</em>
