[Set in Korea]
Song Seon is an illegitimate daughter. Her mother rose to become Chairman Song's mistress by sleeping her way to the top, and Song Yang, her half-brother, sees her as a thorn in his side.
Song Seon is the goddess of Sungdeok Academy: gentle and quiet. Even the mildest person has a temper, but she never gets angry. She is a follower of Lin Jia.
Sungdeok is obsessed with class. Commoners are playthings for the chaebol elite.
Song Seon's fiancé is the son of a top chaebol family. He looks down on her, even detests her, believing she is putting on an act. She always seems so gentle and meek, never losing her temper over anything.
Song Seon's engagement to him was an accident.
Lin Jia looks down on Song Seon's status and is jealous of her.
One last secret: Song Seon's obedient demeanor is an act.
