Sooyoung will soon be taking her grandfather's place as a mob boss. However, her only dream is to become a teacher. With her grandfather's permission, she becomes an English teacher in SM High School, an exclusive school for boys. Her class has its fair share of troublemakers and delinquents and it's up to her to teach them both English and life lessons while keeping her identity secret.

A one-shot featuring SNSD's Sooyoung and Infinite's Sungyeol inspired by Jason Mraz's song of the same title.
