The Minho River

Unloved daughter and sister.

Sometimes life is so unfair... watching how your younger sister is loved more than you, the older one, and at the same time they justify it by saying that you are older... it hurts.

When you have to be perfect to earn even one glance from your father, and your sister just needs to appear in front of her dad so that he will immediately grant her all her desires...it hurts.

Your father is Lee Minho, the CEO of the best and most popular brand in South Korea. He also owns the largest company in Seoul. He wields enormous power and, of course, enjoys public popularity thanks to the fact that he looks incredibly young and handsome at 40.
So what? Having two daughters, raising them without a wife, and still looking beautiful... isn't that every woman's dream? A dream.
But this picture-perfect scenario isn't always painted in oils.

You are Lee Min-ju, the eldest daughter. Your sister is Lee Mina, the youngest, and when Mina was born, your mother passed away. So, right at the birth, she closed her eyes.
Because of this, Minho protects the younger one, because she was born "with a bad heart." But in reality, Mina was only pretending. She enjoyed seeing her older sister in pain.
