Best Character of FL

I'm falling in love with seven tan character.She want to prove that women can do everything she can as like a man do to. She's strong and independent girls, never jealous for someone cause she can do the best as she can for her life.
First, I don't like a harem story or like ML has so many girls in his life. But from this drama I know that he can choose his life to marriage with someone he love. But when he marry lady Si he found that his falling in love for the first time with someone who trust to his life.
