Kim Jae Min used to be a sweet, loving and soft-spoken young girl who was the perfect little princess of the Kim household. I repeat, used to be. Now, she’s the complete opposite and a complete tomboy who goes by the name of Jae and hates anything that is relatively girly. There’s a reason behind her change which even made her start a new life in America. But she’s coming back home to South Korea and that only means one thing – trouble. Especially when it involves her brother, Kim Joonmyun or Suho, and his group of friends who calls themselves Exo.
