Two best friends Marion and Marit are about to finish high school and in a world where status is everything, they learn that an innocent little joke can go viral and change their lives forever.

An entertaining revenge drama follows Haibara Shoko, an ordinary high school girl who vows revenge after all of her family and friends are taken from her. Shoko, an ordinary high school girl, became an internet celebrity after she appeared in beauty streamer Tokumichi Hitoshi's video. However, her classmates, who are jealous of her success, lure her into a trap and film her being assaulted. As a result, the video goes viral and is spread across the internet - making her a target of hate. 10 years on, just as Shoko is deciding to end her life, she happens to see her former happy classmates on TV. At that moment, she vows instead to take revenge on them, and Tokumichi, regretful that he could not help in the past, lends her his support as her partner in revenge.
