i'm looking for this manga I read a while ago and it's completed. It's about these two girls who look exactly alike but they don't know each other. One of them is super rich, and then she pays the other girl to switch lives? In the end they find out they're actually twins and there was a prophecy about them.I really can't remember the manga name D=

Is it Shounen Oujo?

Night gathers, and now my watch begins. It shall not end until my death. I shall take no wife, hold no lands, father no children. I shall wear no crowns and win no glory. I shall live and die at my post. I am the sword in the darkness. I am the watcher on the walls. I am the fire that burns against the cold, the light that brings the dawn, the horn that wakes the sleepers, the shield that guards the realms of men. I pledge my life and honor to the Night's Watch, for this night and all the nights to come.
-Oath of the Night's Watch, A Song of Ice and Fire
