An-Ying
Everyone says teenagers go through rebellious phases, and perhaps Ryu Jae-Hwa is just going through hers. As a girl armed to the teeth with sarcasm, music, and a rebellious streak, she tends to find trouble no matter where she goes. Desperate to spite her mother for the things she's done to wrong her daughter, Jae-hwa set her life on course to spite her. When her mother finally gets fed up with her impudent behavior, she sends her someplace she thinks can force to behave.
That place happened to be Yusung Technical High School.
Found Family troupe (that might change idk)
