I'm searching a fanfic about Kaistal (Kai and Krystal). It's about kai being a born genius. And krystal is the daughter of president of korea (I think, because i forgot the story). Kai's parent was killed and he was supposed to search a technology that made by his parent. Kai is treated by Krystal's father. Krystal fell in love with kai and her father trapped kai to slept with krystal. I forgot the rest of the story... :(( And I badly want to read it. Did anyone know the title of the story? Or did you ever read this story?
