A.N : Hi everybody ! This is a little thing I just wrote that night because it crossed my mind and I couldn't sleep so... here it is. I know it's kinda short but it was not supposed to be a story. I don't know how I really feel about that OS but... it was fun to write anyway.

Hope it's fun to read, too.

With this, I wish you good reading, people !

A door slammed violently, footsteps hammering the floor with belligerency as they never ceized to stop walking, headed towards the bedroom in a haste.

"Mikasa, please !" Annie was pleading as she followed the other girl to the room. Their room. "Please, Mikasa, listen to me ! Please !"

The brunette opened the closet and grasped a pile of clothes that she launched in her suitcase. She didn't answer to the blond. Didn't lift an eye on her either. There was a blank then, heavy and stifling. The only thing that could be heard was Mikasa packing her bag.

Annie stared at her. She did something terrible and she was terrified at the simple idea to lose everything. "Come on, say something..." she breathed desperately before kneeling down next to the Eurasian girl. She wanted to put her hands on her, but she knew she would probably be rejected if she tried. So she put them on her thighs, nervously strocked the fabric of her jeans as she didn't know what to do with her fingers. "I know that you're angry, but-"

"Angry ?" Now there finally was a reaction. "Angry you say ?" Mikasa repeated bitterly as she turned her head towards Annie. "No, Annie, I'm not 'angry' like you said," she scoffed, insisting on the word. "I'm upset. I'm disgusted. I feel betrayed," she added as she raised her tearful eyes on her. "You betrayed me and it's even worse than feeling angry, Annie !"

She threw one of her clothing pretty aggressively on the suitcase.

The blond jumped at the action and felt the knot in her stomach to widen suddenly. "Please, forgive me, Mikasa, it was an accident ! I've never want-"

"An accident ?" the brunette cut, opening her mouth in disbelief. "My girlfriend just fucked with my best friend behind my back and it's no big deal ?" A smirk was ostensible on her lips but her eyes were so cold it was obvious that she felt mad. "Tell me I'm dreaming, Annie..." she said in a feeble breath. "Tell me you didn't sleep with Eren, please."

But Annie couldn't say that. Her throat began to squeeze. Her chin to tremble. She started to cry when she realized what she really did and what were the consequences of all this mess. "I'm sorry !" she apologized, both shameful and disgusted by herself. "I'm so sorry, Mikasa !" she sobbed, extending a hand on her lover to touch her in a hope to reach her heart. "I was completely drunk !"

"Holy shit !" Mikasa shouted as she straightened up, rejecting the hand with a violent slap. She tried so hard to retain those tears that wanted to fall from her eyelashes, but she kept fighting against her sorrow. She didn't want to cry for that girl. That cheater. "You disgust me."

The voice that had spoke was cold. The words bitter and harsh. Annie felt her heart being taking down of her chest. She cried harder. It was painful.

She wrapped her arms around her own chest to retain her body from shaking. She couldn't stop herself from crying. Words were useless, but what else could she do ? It was the only thing she still had. "Please, Mikasa, let me redeem myself..." she lamented miserably between two sobs. "I still love you. I'll do any-"

"I'm leaving," Mikasa cut, obviously indifferent to her tears and explanations.

Annie suddenly forgot how to breath. "What ?" she demanded, her tears still flowing but her voice mute.

"I'm leaving," Mikasa repeated, grabbing her suitcase to leave the room. "I don't want to see your face anymore. It's over."

Annie shook her head vigorously, a hand on her broken heart. She couldn't believe those words. She couldn't believe there was some end on their story. "No, please, Mikasa, don't do that !" she pleaded once again. Endlessly. "Don't leave me ! Please."

The Eurasian lowered her eyes and smiled bitterly. "You cheated on me, Annie. You betrayed me. I can't even look at you in the eyes," she murmured, her smile fading from her lips as she passed her to head towards the front door. It was as if she wasn't listening any words Annie used. Like her ears wasn't receptive of that voice she loved so much before.

Annie's stomach twisted. Her heart skipped a beat. "Eren was a big mistake, I know that !" she exclaimed to protest. To retain her girlfriend. "But it was just once, and we were so fucking drunk..." she started to cry again when she thought about that night. "I didn't even realize what I was doing, Mikasa..." she said as her body trembled in the same pace of her sobs. She hid her face in her hands. "I'll do anything, Mikasa ! Just trust me ! I don't want to break up with you ! I don't want you to go !"

"Fine," Mikasa replied sternly, making Annie's eyes emerged from her shaking hands. "So you're leaving."
