Coriolanus was possessive. This was a fact he could not deny; whenever he had something he viewed as his, he wouldn’t let it go. This rule applied tenfold for people. Especially Sejanus Plinth. Nobody else was allowed to have Sejanus.
See, it wasn’t that Coriolanus particularly liked Sejanus, in fact he’d argue with himself that he hated the boy, but that he had a strange infatuation with him. An obsession, if you will. The brunet was just so curious. He was loyal, sweet and so incredibly devoted to Coriolanus it almost made the blond sick. Ever since that day on the playground, where the blue eyed boy had chosen not to join in with his peers taunts, Sejanus had stuck to him like glue. He’d follow him around in the hallways, sit next to him in classes, eat his lunch across the table from him, greet him with a good morning and bid him goodnight every day they saw each other and bring him his ma’s cooking as if he was trying to persuade Coriolanus to stay.
Ever since that day on the playground, Sejanus had irrefutably belonged to Coriolanus. Sejanus was his boy and he intended to play that to his advantage in every way possible. Snow hated Sejanus because he was district, but he was not stupid. The Plinth family had money: lots of it. Alienating himself from that opportunity would be a let down, no matter how annoying he believed the other to be.
This was why, one day, when he’d gotten to class late due to a mishap at home in the morning, he’d been shocked to see that his seat had been taken by another student. He observed the scene for a moment, fighting back the urge to scowl at the boy sat next to Sejanus, and felt a rage like no other settle heavily in his chest at the sight of Sejanus chatting along with his newfound seat mate contentedly. How dare he. Doesn’t he know Sejanus is mine? Coriolanus’ mind screamed, storming over to an empty seat with badly masked anger.
He was being rather obvious, footsteps heavy as he took a seat, but Coriolanus just couldn’t help himself. Sejanus had never dared do such a thing before! Nobody else had even been interested in him before! What was with the sudden switch up?
Coriolanus had to tear his eyes away from the pair when he noticed Sejanus pausing to glance over at him, clearly having noticed his gaze on him. Not that it wasn’t obvious, because it absolutely was. Coriolanus was staring at the scene before him with such intensity that he was sure if looks could kill both of those boys would’ve been dead five minutes ago. He tried to shake it off, looking down at the work he’d gotten out in front of him rather than at Sejanus and his little friend. Except, the longer he stopped looking at them, the longer he stopped having visual reassurance that the person sat next to Sejanus was not doing anything to the boy that was reserved for Coriolanus only, the blond found he only grew more and more irritated. He was gripping the desk hard, knuckles white with the force of it, and biting the inside of his cheek to stop himself from getting up and saying something he’d regret. He’d never felt so out of control before, emotions going completely haywire. Why was Sejanus Plinth affecting him so much? Coriolanus was a Snow, for god’s sake! He shouldn’t feel so strongly about a pitiful district boy at all.
Except, he did. Because Sejanus Plinth was his. Coriolanus’ gut twisted at the thought of the brunet ever belonging to anybody else. He’d sooner die than allow that to happen.
The end of class couldn’t come fast enough, Coriolanus rushing to pack up his things and swiftly follow Sejanus out of the room. He followed him down the hall, gaining ground on the other quickly, and peeked around the hallway to check nobody was watching before grabbing the other, pulling him into the nearest bathroom and locking the door behind them. He made quick work of slamming Sejanus into the nearest wall, hands gripping his uniform so tightly he thought it may rip.
“What was that.” Coriolanus spoke, voice gravelly with anger. He felt high on the power he currently had, watching those big brown eyes fill with panic, then confusion, and then flip back to panic again. Sejanus was struggling against him, but despite being physically larger than Coriolanus the blond’s rage fuelled strength was not easy to fight against. Snow loved it, loved watching his boy struggling against him. Back where he was supposed to be.
“I- What do you mean? What was what?! Coryo- please let go-“ Sejanus spoke, voice so pitifully weak as he stared at the other boy in disbelief.
Coriolanus scoffed, grip tightening and pushing Sejanus harder into the wall. “You know exactly what. Hanging out with him. That spot is my seat, Sejanus. I sit with you.” He sneered, eyes wide and positively feral. Sejanus had never seen Coriolanus act this way before and frankly it terrified him.
“I didn’t- I didn’t ask him to! He just came and sat down! I swear, Coryo. Please let me go!” Sejanus explained, heart hammering in his chest and only contributing to Coriolanus’ power trip. “I swear, usually he just throws insults at me like everybody else. I don’t know why he was being nice to me today.” Sejanus is so honest, so desperate for Coriolanus to hear him out and stop this behaviour which is so unlike him. Coriolanus almost pities him.
The blond boy studies the other for a moment, anger and jealousy still burning in those intense blue eyes, before he finally sighed and let Sejanus go. “Fine. But you are mine, Sejanus. You hear me? You’re mine.” He snapped bitterly, stepping back ever so slightly to let the brunet regain his footing and calm down a little.
Sejanus seems taken aback by his words for a moment. Just for a moment. Then a warmth spreads across his face and those eyes fill with such intense adoration that Coriolanus has to fight off the urge to heave. God, he had no idea how Sejanus could even look at him in that way after such and outburst. “You were jealous,” the boy comments plainly, the smallest of smiles on his face. Damn Sejanus and the stupid way he always seemed to end up more enamoured with Coriolanus after every single interaction. It was disgusting.
“You’re mine.” Coriolanus states, so matter-of-factly that there is no room for a single ounce of argument.
“I am. Yours.” Sejanus agrees, seemingly over the moon with the conclusion.
Stupid Sejanus. Stupid, naive Sejanus with his stupid, pretty smile. Coriolanus hated him.
(At least, he wanted to.)
