Aera is a Korean little girl with 2 older brothers, who are twins, Haneul and Minjun. One day, a civil war happened and Haneul decides to fight on the capitalist side and Minjun, on the communist side. Both brothers are fighting over their little sister because they each want to keep her for what they believe is for her own good. Haneul wants her to live on the capitalist side, while the other thinks the opposite. What will Aera do? Who will she choose to be with between her 2 siblings, especially when she has no idea about the political problems happening in the country? (Part of the story is inspired by another story I read)
