Kujou Sara's life has always been a straight line. She was studious, diligent, orderly, and responsible, never breaking a rule, and always doing as she was told. She had no problems with her life, she liked it just the way it was, at least she thought so, it was calm, peaceful, simple, and ordinary. Sure, you might say it was a boring life but Sara never really thought of any other way her life could have gone, until she met a certain "blockhead," little did she know her ordinary life would change the moment she met him.
