Naomi is a simple person. She is an ordinary girl but often misjudge by others because of her weird actions. Although she's often hurt by the people around her, she never hated anyone in particular. No one knows she's an angel from above. God sent her to earth to befriend a girl who never believed in God, Liah.
The time in heaven and in earth are far different from each other. Naomi was given only 14 days to stay on earth. Before she left heaven and came on earth, another angel, Angela gave her a mirror that serves as her clock connecting earth and heaven's time. Anyone who faces the mirror will be able to see who she really is.
