Hyoyeon is a 24 year old girl who lives with the all famous EXO who were kingka's at the most expensive school, S.M High. She isn't really considered a maid or a servant. More like a girl who was living on the streets and EXO would let her be their roommate if she cooks for them, clean their mansion, help them get dressed and ready, no one would call that a maid..Right? Hyoyeon was more like.. EXO's favorite and only NOONA. Hyoyeon is like EXO's Umma. They love when Hyoyeon makes all these jokes when they were bored. How they would play games late at night. Watch movies together. EXO has the perfect NOONA everyone would want. No one even knew that EXO had magical powers. Only their Noona knew this. This. Is just the BEGINNNING!!!!!!
