It only takes a Genius *Brothers Conflict*

Ema has been lying to her brothers since she moved in with them. How will they react when they find out that Ema has a sister and she happens to be smarter than all of them combined. Rated T just in case of future language and sexual context in other words lots of fluf. This includes all other characters. Oh and Ema's sister graduated high school when she was eleven years old and was already attending Tokyo University at that time as well...She is considered to be a super genius. PS I SUCK AT SPELLING AND PUNCTUATION SO IF YOU SEE ANY LET ME KNOW JUST DON'T BE RUDE ABOUT IT PLEASE.
