You are the Moon Goddess, waiting for your true love, for many centuries you still yearned for him, waited for him, but you know he will be there, you waited and waited hoping he'll be there, your parents, arranged a marriage for you, not knowing who it was and you agreed for your people's sake, little did you know, it was..him
