I am willing to be your sun and shed the warmest sunshine for you in the cold winter.
I am willing to be your moon and light your way home in the dark.
I am willing to be your navigator; I am willing to be your escort. Wherever you want to go, whenever you need me, I will be with you 24 hours a day to show you the way. Whenever you encounter difficulties and dangers, I will protect you at the first time.
