“Sweet Revenge” Korean web drama tells the story of Ho Goo Hee, a 17-year-old teenage girl who just started her first year of high school. But, she constantly gets bullied by other students just because her name sounds like the word ‘loser’.

Ji Hoon is the most popular boy in the school and has come to save her many times than he would like to. Jung Deok Hee is her classmate and becomes her only friend. She has a crush on Cha Eun Woo and calls herself “Eun Woo’s wife.”

Eun Woo is a popular K-pop idol and a family friend of Goo Hee who treats her like a sister. One day, Goo Hee found an app called ‘Revenge Note’ in her phone. The app asks her to write the name of someone who bullies her, and she does so. Suddenly, unfortunate and embarrassing events starts happening with that person. After seeing this, Goo Hee decides that it’s time for payback, but instead of getting better, things turn out to be more complicated for her.
