Hyoyeon was on her last year of high school. All her friends are all excited, talking about Universities where they want to apply and the life of college students that awaits them after graduating. But there she was on her chair, staring at the picture of her ultimate bias as she listened to his group's songs on her phone. Lost in her fantasies of him, daydreaming without caring about what happens next. What does she wants to do after high school? To marry EXO's Kai.

KaI on the other hand, just started his first year in middle school. Though he goes to school irregularly due to his busy schedule being a member of the popular boyband, EXO, he always does his best in studying for him to be able to improve in his craft. The last thing he wants to deal with was a sasaeng who wants to know everything that he does. He knows that fans are important and he should treasure them but at least, as a human being deserves some privacy right? And then he met Kim Hyoyeon.

A sasaeng. An idol. What would happen if their destinies meet?
