When the Sky Falls.

Celica is the daughter of a wealthy family. Her father owns a big house and has a lot of money. However, they are living in a small house at the country side and they plan to move. Tewada's family wants to go first to prepare the new house for Celica's family, which only includes her dad and herself. When Celica and her father are on their way to the new house, some assigned bad guys try to kill them and Celica's father dies. Before he died, he burned his daughter with a symbol stamp to represent that she is his daughter. Tewada's family thought that both of them died and they pretended that Tewada is Celica's father's son in order for him to get the inheritance. Years later, Celica and Tewada are both grown up and they meet again.
