Eren and Levi are finally get into a romantics relationship, but one thing Eren fails to notice is that Levi quickly grows an obsession with him. Soon enough it's too late, and now Levi won't let Eren even hang out with his friends. Jealousy takes over Levi and a punishment is made every time Eren disobeys his orders to stay away from the other soldiers. ~<>~ WARNING: Triggering events (maybe), blood, strong language (because Levi), not-too graphic scenes, implied smut, and character death.
