For Leyla and Korbin, I was thinking I'd Come for You by Nickelback, because of these lines:
By now you know that,
I'd come for you,
No one but you,
Yes I'd come for you,
But only if you told me to,
And I'd fight for you,
I'd lie its true,
Give my life for you,
You know I'd always come for you
Because he strikes me as the protective type. ;'D
