Go Jieun is your typical seventeen-year-old high school living in modern Korea. Her life consists of doing things like any other teenager would do now at days: playing video games, reading webtoons, and watching K-dramas, and fangirling over their favorite actors. 

Lately, she has been obsessed with a web drama called Love Revolution, a drama related to the high school life of the main protagonist, Gong Jooyoung, and his love interest, Wang Jarim. She biased the main protagonist and the other character called Yang Minji so much that she wished happiness for both of them. But...after an incident....she ends up in the web drama by another identity, Choi Kyungmi, an extra that she didn't know would exist. 

Now in the body of Choi Kyungmi, Go Jieun must find a way back to her world before the story of the web drama ends and without making any changes from it. 

Will she be able to return to her previous life?
