Yoon Ji Hyo has been living off a special rose ever since she was born. She was cursed by it because her parents were rude to a woman, who was a witch. They didn't knew she was a witch until she told them. She told them the only way to cure Ji Hyo's curse was if the parents apologize to her. Unfortunately,  they didn't believe her. They ignored the witch until they realize a few years later, a dying rose next to their ill 11-year-old daughter. They were never accepting the witch's proposal to cure their daughter. They were stubborn.  Their solution was to leave their normal son and their abnormal daughter. Their 14-year-old son, Yoon Doo Joon, will never forgive them.

 Hyunseung has been his bestfriend ever since childhood. He and his parents would always check up on them instead of sending them to an orphanage. Whatever happens to the rose, happens to her. She's invisible and shy at school, but if anyone confronts her, she'll be vicious like her thorns. Even though her brother is a kingka, she remains invisible to everyone. Hyunseung, who is also a kingka, tries talking to her, but they didn't become that close, only as acquaintance. Can Doo Joon other kingka best friends become close to her? Especially the cute, cheerful Yoseob, who annoys her with aeygo?
