Creative Execution

The drama starts from SNS posts of the characters. In the morning, they go to school, at the same time as real students. On breaks, they enjoy their time with classmates. At 4:00 pm everyday, a YouTube drama series starts. Users can peep into the characters’ after school life, where the story majorly progresses. The whole story connects through the characters’ SNS posts and YouTube dramas. For example, an Instagram “Stories” post of a date, leading to a fight between the characters in the YouTube drama series the next day. Or a lie revealed in the YouTube drama, exposed from a location information on a photo posted on “Twitter”. The drama continued for 30 days, crossing over various media platforms.
