Arghhh. I love this pairing so much after reading all the really angsty doujinshi on them. This short fanfiction was something I decided to write in the spur of the moment. It's based on a doujinshi I read which can be found here:

*Heart shatters into a million pieces*. It's based on Levi's perspective of the whole event. I might decide to write a longer continuation depending on whether i'm in the mood for writing. Anyways! I hope you enjoy the yaoi!

(Artist's Summary of the Doujinshi: A 15 year old Eren just wants a kiss from Levi, but was rejected. Levi is actually a very gentle person, but because of this gentleness, he knows deeply how fragile life in this world is, so he tries to avoid having deep feelings for anyone, using harsh means to get Eren to give up. Eren is a stubborn child, and he interprets Levi's rejection to mean as him not having any feelings for Eren. So, on the day that humanity exterminated the titans, for the sake of not letting his titan self be a burden to the corporal, Eren chose the end he thought was best for himself. Which was to crystallize his own body.)

"Eren…" Levi whispered under his breath as he glanced at the young boy who was trapped within his crystal cage. He lightly kissed the ice-cold crystal and placed his hand gently on the surface of the crystal that covered his lips. He had come here every day and night unfailingly, for the last year.

I'll come again… Every night, every morning to give you the kiss that you desired so much…

Levi remembered how whenever they spent the night together, Eren's face had always instinctively reached closer to his corporal's lips. However Levi had always managed to turn away at that moment, or avoid contact with the young brunette boy. He would always tell him that he was just a 'brat' and that he was 'disgusting'.

I truly did believe that he was just a brat when we first met… I wonder when that changed.

Levi had always been attracted to Eren sexually. He didn't know why, but he always felt lust whenever he glanced at the teen. He wasn't ashamed to act on it either. Eren had always been so submissive and attentive to his corporal that it was easy for Levi to get what he wanted.

He was really just like a dog.

A simple tool for exterminating all the titans, and at night a simple toy that Levi liked to use to relieve and give himself sexual pleasure, it really was nothing more than that. Levi simply didn't care about him.

However, he always knew that the teenaged boy had special feelings for him, and in the beginning he remembered thinking that it was such a nuisance. However, whenever the teen had tried to kiss him, Levi would always feel his heartbeat accelerate unnaturally, and the urge to press his own lips to the Eren's was overwhelming him.

He began to feel scared, scared that these emotions would overwhelm him entirely. He had to stop them, so Levi tried to be as cruel to the little brat as possible. These sorts of feelings were only a burden in this lifestyle; A lifestyle that revolved around death.

Somehow, everything just slowly began to become different. Eventually, the words 'disgusting' never entered his mind. It was replaced with 'adorable' and 'irresistible'. He didn't truly believe Eren to be a brat anymore either, he did everything he could to keep his hands to himself when Eren and him were in a room together.

Levi's heart clenched when he realized what the last words he had said to Eren was before he was crystallized. He remembered slapping the teen's face when the teen had tried to kiss him and calling him filthy. In truth, he really wanted to kiss Eren. But his brain and resolve had told him not to. He remembered how he wanted to kiss Eren's forehead when he had started crying over the rejection, however Levi had told himself that he had to be cruel, he continued thrusting violently into the young teen until his eyes were red from crying.

He kissed the crystal surface again and again; hoping desperately that the teen could feel it from inside this cage.

Eren…! I'm so sorry. Please forgive me.

He hated himself. He had been so cruel to the only person he had ever loved.
