One mistake turned into eternal hatred. For more than ten years, she had been doing her job normally, but when she was young and ignorant, she made the same mistake as any young girl: falling in love with him secretly. The result... Was not satisfactory. Her adoptive father was killed by a friend, and she almost died, but... She didn't do anything, right? What about him? Tell her: "This is between you two and has nothing to do with me." It has nothing to do with him? He never explained, and then, she left. Between reality and illusion, she accepted reality. This is a great choice. Because she chose the cruel reality, she accepted the pressure and changed from then on. Therefore, from a cheerful and gentle girl, she became a ruthless king.
