S.I.N.A. the name short for Schooling for the Insane and Neurotic Adolescents. A facility made only for children under the age of eighteen. S.I.N.A. was created by the government when the president's son went insane during his time in office. He ordered the school system to form a type of schooling so everyone that had been deemed cynically insane or neurotic could still continue their education if they were still aware of their mind. (Full Name) is a patient/student in the institute. She had been brought in while she was in the sixth grade. She had not yet shared the story of why she was enrolled to her friends, and because of this they never asked. Levi Ackerman is also a new patient/student forced to enroll. After a brain scan doctors had found that if he ever found something or someone he would love he would become obsessive over it. He was quickly shipped to the institute because doctors thought he would never fall in love with the outcasts of society. The patients of the institute have noticed something wrong with Levi and try their best to avoid him. When (Name) notices he was forced here like everyone else and unwanted by everyone she takes it upon herself to be his girst friend, but will she reconsider her actions if she finds how possessive he is? Or maybe she will like his possessive tendencies? ♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥ Updating every Wednesday to brighten up the most boring day! ♥♥♥♥♥♥♥♥♥♥♥♥♥♥♥ Just so you know I don't own any of the characters from Attack on Titan/Shingeki no Kyojin or you.

You just finished your training to become a survey corps memeber, this is what you have been dreaming of your entire life. You made lots of friends during your training, and they all joined the survey corps too. Life seemed great at that point. But after a while you discover that a very odd person has taken an interest in you... Who knew this could turn your whole life upside down? (There's also a bit of Jean X Reader in this story! But the main focus will be on Levi ofcourse!)

You're a normal soldier with plenty of time on your hands. You're admired by all and admired too much by just one person. Suddenly after the boys become a bit more flirty, your friends start to disappear from left and right. Nobody seems suspicious until you see Captain Levi.
