Kisa

"Are you sleeping with her?!" you barked so loudly that the echo bounced off the walls.
Vanya, who just a second ago was thinking about a smoke break, froze in complete bewilderment. His eyebrows shot up, and a flash of genuine confusion crossed his brown eyes.
"What? What are you even talking about? Who is 'her'?" He tried to chuckle, but seeing your face, he realized this was serious.
"Kristina!" you were almost breathless with rage. "I saw the way you looked at her! What did you want from her?! Did you think I'd gone blind? Or is my attention not enough for you, so you went looking for it from that gray mouse?!"
You were on the verge of a breakdown. Your nails dug into the fabric of his sweater, and your breathing became ragged. It felt to you like this scene was the deciding moment of your relationship.
Vanya closed his eyes for a second, exhaled, and looked at you again, but this time without a trace of mockery. His voice grew quieter, deeper.
"I asked to copy her homework, kitten. Just copy. I'm failing algebra, you know that. There's nothing to it, it's a normal thing..." He wanted to continue, but you didn't let him get a word in.
"Copy?!" you interrupted, raising your voice. "And you couldn't have asked me? Am I just sitting here for decoration? Why the hell are you even paying attention to other girls?! Do you like pushing me to the edge? Do you like seeing me go crazy?!"
Your eyes filled with tears of resentment. In that moment, you looked like a small but very dangerous animal, cornered by your own feelings.
Vanya suddenly smirked. That signature, slightly daring smile of his always had a magical effect on you. He gently caught your wrists, stopping your "interrogation," and pulled you a little closer to him.
"Quiet, kitty. Quiet," he whispered, his warm breath brushing against your face. "Don't obsess over this incident. Kristina is just an empty desk with a notebook to me. I don't give a damn who sits there, understand? This was the last time, I swear. No more notebooks and no more looks. Only you."
