They obviously have exactly the same face, and they obviously have the same blood flowing through them. One is kind-hearted, while the other is as poisonous as a scorpion. Childhood is miserable. One strives for self-improvement and relies on his own efforts to win the future, while the other regards the man who killed his father and took his mother as his father and covets glory and wealth. Maybe because they share the same blood, they fell in love with the same excellent boy but had a sworn hatred. Sadly, because of the grudges of the previous generation, the two sisters who were originally in love with each other had to stage a tragedy of fratricide.
