On the day the orphanage collapses, Hye-sang finds out that Sa-wol is to be adopted by her wealthy biological father instead of her, since a DNA test reveals the mix up between them.
Eager to be raised in upper class society, Hye-sang traps the orphanage director, who is also her true father, in the collapsing building with Oh-wol to hide the truth.
However, when Sa-wol ends up being brought into the family as well, Hye-sang starts tormenting, blame shifting and burying the truth, to make herself the better daughter.
