Original story, not my art.
*DISCLAIMER* This story may contain, drug use, alcohol use, smoking, violence, language, and sexual content. It may contain sad backstories, so this is your full Trigger Warning (TW). I'll try to warn you with a TW before sad stuff. If you do not like this, don't read on.
Levi Ackerman is a total douche. He acts like he's better than everyone else (granted, he is). One day his car breaks down and Eren, owning his dad's business, 'fixes' it. After coming back regularly, they start to share a connection.
