NOTE: We just finished rewriting this story and added chapter 3 after a long time, two years perhaps? Anyway, thank you to the subscribers who stuck with us through the whole process! You guys are the best!

 Krystal Jung, the seventeen years old master of pranks. She has a long rivalship with Minho Choi and neither is willing to back down. When she was very young, Krystal's parents passed away in a car crash and ever since, she has been raised by her grandmother, Victoria Jung, the president of Jung Cosmetics.

 Amber Liu is the definition of a coldhearted rebel who fights until she can barely stand. With a dysfunctional family, she used to skip school and run off with gangsters until she met Krystal who turned her life around and made her see the bright side of the bridge. Now, at the age of eighteen, she is trying to change her habits so she can get into a good college and land a well-paying career.

 Sulli Choi is another one of Krystal's best friends. Around the school, she is known for her happy-go-lucky personality and nobody had ever seen her cry before. At the young age of seventeen, she is not ready for the future and she wishes to remain in high school with her friends forever.

 Luna Park, the seventeen years old heir to Yalushi Breads, a world famous bread company, is one of Krystal's best friends. While she looks like a cold queenka, she is really timid and sweet.

 Minho Choi is a kingka at Krystal's school who makes it his life's mission to torture her. He is seventeen. He has a childhood friend that he left one day and never found, but he never forgot her.

 Jonghyun Kim is a kingka at Krystal's school and he holds the record for being a heartbreaking player, having already dated almost all of the girls in the school. But he claims that the only reason he does so is so he can find the perfect woman for himself.

 Taemin Lee is a kingka at Krystal's school but unlike the others, he prefers to prank, not bully. He has a lot of admirers and true friends, unlike his friends who only have followers. He is often compared to Sulli, which he dislikes.

 Key Kim is a kingka at Krystal's school and a part of Minho's group. He is a quiet and serious person. His dad is the owner of a world famous bread company called Kim Breads and his grandfather, Onew, owns a seafood restaurant called Joy K's Seafood Restaurant.

 Lucy Kang is a queenka at Krystal's school who came back from the states. She is seventeen. While she thinks she is the top and scariest queenka, she is not because, unbeknownst to her, she is actually following the orders of Jiyeon.

 Jiyeon Park is the cruelest queenka who will do whatever she can to get what she wants. Currently, she is dating Jonghyun, the only guy she truly loved. Losing him will break her. Her father owns the five star mall called Premium Dreams Mall.

 Ri-ah Lee is another queenka.

 He Yi Yoo is the nice queenka.
