You know whatever happens, I'll be right by your side.
I think of you everyday. By your side I promise to stay.
I don't care what other people think about us. I love you and will always be by your side.
I promise to always be by your side. Or under you. Or on top.
I promise that I'll be by your side through good and bad times. I'll be there for you no matter what.
You were always by my side and I will always be by your side.
