New Feelings and a Promise [Rivaille x Reader]

      "Colonel." In the open doorway stood Corporal Rivaille, the same dull expression on his face always. 

      "What is it, Rivaille?" You questioned as you put your handkerchief back in your pocket. 

      "Commander Irvin said that he would like to see you." You stood up, and Rivaille walked you through the door. As you walked past once again, people noticed that you were walking with Rivaille. You both had the same stony eyes and bored expression. You even walked at the same pace even though you were a little shorter than Rivaille. You heard many whispers, and there was one that stood out. 

      "They're practically twins!" You heard a brown-haired girl whisper. The girl next to her agreed, and you gave them a menacing glance. They both gulped and stepped backwards, giving you and Rivaille space to walk through. You looked at Rivaille, and sure enough there was a slightest hint of smirk on his lips. You shared the same expression, and it was quite surprising to the cadets watching you two walk through. Once you arrived at Irvin's office, you both saluted. 

      "Commander!" You both yelled, feet apart. Once Irvin dismissed your salute, you both stood straight, arms folded behind your backs. 

      "Colonel [f/n] and Corporal Rivaille. I have some horrible news for the both of you." You both were now at full attention and listened to what the Commander had to say. "Titans have broken into the Trost District and we need you both to hold off the titans while the citizens evacuate." You both nodded, understanding what he was saying. He dismissed the both of you, and once you were out the door, you sighed. 

      "What is it, [Name]?" Rivaille and Hange were the only ones who could call you by your first name. After all, you have known Rivaille since he was an underground criminal, and you've known Hange since she hated the titans. And that was a very long time. 

      "I don't know, a little nervous I guess." You shrugged, and Rivaille narrowed his eyes at you. 

      "This isn't like you, [Name]. You're never nervous." You looked at him, eyes slightly widened. He was right. You were never nervous. 

      "I...I don't know what's going on over here." You gestured towards your heart. It was beating fast, and you don't know why. You have never experienced this feeling before, and it sure was strange. Rivaille narrowed his eyes even more, (if that's possible), and studied the area you were pointing at. 

      "[Name]...is there someone you care about?" You widened your eyes at the statement; you have never been asked that before. 

      "I-I don't know, Rivaille." He studied your face and said another thing. 

      "You're even stuttering, [Name]. You never do that." You took a step back, widening your eyes even more. That fact was also true. What is this? You weren't sure if you liked it or not, but you dismissed the topic with a wave of your hand. 

      "We'll talk about this later, Rivaille." Those were your last words before you walked off towards Hanges office. "Hange. I have a question to ask you." The brunette turned her head towards you, papers in her hand. 

      "Sure, [Name]. What is it?" You walked towards her, and sighed. 

      "I don't know what's going on over here." You gestured towards your heart once again, and Hange studied the area. 

      "When does this feeling happen? When you're with Rivaille? Hmm?" She wiggled her eyebrows and nudged you with her elbow. You blushed and stepped backwards. 

      "I've never seen you do that either, [Name]." You jumped at the icy voice and the sudden contact. "What is that on your cheeks?" He cupped your cheek with his hand and stared into your sparkly [e/c] orbs. "You're burning up, [Name]." He held your face so close to his, and it made you even redder. He seemed confused as to why you were so red and hot, and you broke the position by removing his hands from your cheeks. 

      "I'm fine, R-Rivaille." You looked sideways and saw Hange give you a thumbs up. You rolled your eyes. 

      "Are you sure, [Name]? You've never stuttered saying my name before, either. I'm worried about you." He stared at you once again with his stony grey eyes, and studied your expressions. Having studied your face enough, he turned towards Hange, and she gave him some paperwork. Soon he was out the door, and the door shut behind him. You drew in a deep breath. 

      'Was I holding my breath this entire time?' You asked your inner self. You apparently were, and you really needed that breathe of air. 

      "[Name], you're in love!" Hange squealed, jumping up and down like a happy little girl. 

      "Love?" You questioned, a confused look on your face. 

      "Yes [Name]. Love. When a girl loves a guy, she gets all nervous around him and doesn't even remember how she used to act around him. That's your situation right now, [Name]." You were slightly confused by what she was saying, but soon enough it made sense to you. The blushing, the nervousness, the stuttering. You understood now. 

      "Thanks, Hange. I'll see you later." You waved goodbye, and headed towards Rivailles dorm. You knew around this time, he'd be in his dorm cleaning. You knocked on the door, and Rivaille answered with a quick "come in". You opened the door, and blushed at the sight before you. Rivaille was shirtless, wearing nothing but his pants (without a belt!) and the straps. You looked down, and admired his body. He was perfectly toned, not too much and not too little. He was perfect, beautiful even. He looked at you, confused again. 

      "[Name]? What are you staring at?" You turned even redder at this question, and shook your head quickly. 

      "N-nothing, R-Rivaille." You replied quickly. You cast your glance sideways, trying to avoid looking at his beautiful body. 

      "You're stuttering again."

      "Really?"

      "Yes." It was awfully hard to not look at his body, but you tried your best to look at his face. 

      "So I asked Hange about this." You pointed at your heart and your red cheeks. 

      "Oh? What did she say?" You gulped. 

      "Well...she said I was in love with someone." Rivaille narrowed his eyes. 

      "Really? Who?"

      "She said its the person I'm next to when my heart beats fast, when I stutter, and when I get nervous." Rivaille thought for a while. He didnt get it. You sighed. "It's you, Rivaille. I'm in love with you." He stared at you for a long time. He then turned around, put on his shirt, and headed out the door. You sighed. 'Where is he going?' you asked yourself. 

      You walked briskly towards Hanges office. Now you had to ask her. Your heart was beating fast and you were awful nervous. 

      "Hange." You said as you walked through the door. 

      "Yes, Rivaille?" She said as she placed down some papers. 

      "What is this I'm feeling here?" You pointed towards your heart, and she grinned. 

      "You should go ask [Name] about that." You turned around once again, and headed back to your dorm. 

      You were sitting on his bed, head in your hands. 'What did I do wrong?' You questioned yourself. All of a sudden, the door burst open and in came Rivaille. 

      "[Name]. What is this I'm feeling?" He pointed at his heart, the same way you did. You blushed. 

      "Love, Rivaille. Love." Now it was his turn to share a bit of the ruby on his cheeks, although he was better at controlling it. He shut the door behind him, and walked towards you. He took off his shirt once again, and you blushed again. "What...are you doing?" Your breath hitched when he lightly touched your neck. 

      "Showing my love for you." And with that, he put his lips on your neck and nipped away. 

      "No, Rivaille. You missed." You pulled his lips off of your neck and pulled him towards your face. You both kissed passionately, his hands in your soft, [h/l] [h/c] hair and yours in his soft black hair. You both finally came up for air, and you trailed your finger down the middle of his pectorals. "Sorry Rivaille. Not yet. We have a mission tomorrow, remember?" He groaned in annoyance, and sat on his bed. 

      "Then when we get back, [Name]?" He gave you a playful smirk, and you turned red. 

      "Yes, Rivaille. When we get back. Promise." And with that, you pulled his shirt over his head, gave him a quick peck on the lips, and headed towards your dorm. Once you shut the door behind you, you collapsed onto your bed, reflecting on what just happened. You turned even redder, and smiled to yourself. 'Once we get back, Rivaille. Promise.'
