Fight me - Rivaille x reader

There was a consistent pattern when you sparred with anyone. Considering you were one of the most elite and proficient of the 104th training squad, it was understandable for the boredom to slowly takeover the concept of the training
.
“(Name)? Are you even listening to me right now?!” an impatient groan erupted from Armin as he waved a hand in front of your face
“Hm? Sorry, Armin, I must have drifted off a little” you smiled at him.  He smiled back at you and then looked in a different direction where his eyes widened. Bewildered, you turn to face where he had been looking to see that Lance corporal Rivaille was strutting toward the training field, head held high. Everyone gradually realised that Lance corporal was there and immediately stopped what they were doing to salute, as did you.  

He stopped to glare at each individual that stood before him, judging them silently. He stopped at you for a couple of seconds and you could have sworn that the glare that was previously on his face had disappeared.

“Alright brats” he announces “seems that Shardis hasn’t turned up so I’ll have to babysit you. Now get in partners and practice.”
An agitated sigh left your lips as he mentioned the word 'practice'. Of course you couldn’t spar with poor Armin it wouldn't be fair on him, so you told him to go and find a better partner. In the end you ended up without one since everyone seemed to have an equal match.

“Oi!” an annoyed voice tore you away from your thoughts “why aren’t you practising?” it was corporal. To be honest you couldn’t really tell him that you were too violent or too skilled so you came out with something along the lines of “no one wanted to spar with me” and shrugged it off

Unfortunately for you,  he had decided that he would spar with you regardless of your desire not to do so. Despite that most people were busied with infighting, you couldn’t help but notice that there were a few peering eyes, seeing what would happen if the two of you were to spar.

“whenever you’re ready” corporal said casually.
First you lunged at him, bringing your hand round to hit him but he dodged and in return grabbed your hand and pulled in back so you couldn’t use it. You kicked the back of his leg to trip him up but he brought you down with him, so that your back was on top of him. You stroke an elbow into his stomach so that he would let go of your arm. You span around to face him, straddling him and grabbed his wrists. Just as you thought you had won, he smirked and grabbed your hands flipping you and pinning you to the ground making you let out a small gasp.

You both panted for air after he finally let go and he got up lending you a hand help you, which you gladly accepted. Once you stood up he stared deeply into your big (e/c) eyes and you couldn't help but feel your face burn up seeing as there was very little space between your two faces.

“What was your name, cadet?”  He asked, moving away a little
“(Name)(Last name)” you answered still recovering
“You’re very skilled, (Name). You should consider joining the recon corps when you’re done with all your training.” He turned away from you and began to walk away.
As you turned to actually comprehend your surroundings you realise that everyone is staring at you with the same bemused expression.
