Mein Liebling, you have respected my wishes often and kept your hair long and red for me. You have done your very best to please and satisfy me.
Granted, I'm not the monogamous kind, but I think that you will find, that I will always treat you well, and try not to be unkind.
Exclusivity is not required for love to bloom, as you can see, as permanence and romance shall be kept for just you and me.
Remember, though I may pursue others on a lustful endeavor, that they don't get the greatest part: they don't get forever.
