Jean Kirstein was a very jealous guy. He hated it when his girlfriend, Y/N L/N, was around other people, mainly guys. Sure, it was normal for people to get jealous, but not on a very high level like Jean.

Whenever a guy would try to talk to Y/N, Jean would always get in their face and insult them. On some occasions, he'd even punch them. The only guys that were allowed to be around Y/N most of the time were Connie and Marco, since they were Jean's friends.

Once, Armin, the school nerd, had gone to Y/N's house to help her study since she had asked him to. When the next day came, Jean had approached him and punched him in the face, breaking poor Armin's nose. After that, Armin never went near Y/N or helped her study again.

Most people learnt that going near Y/N when her boyfriend was around would probably result in a bunch of insults being thrown out or a punch to the face, so they stayed clear of her. However, there was still those people who still spoke to Y/N despite what happened to others before.

One day, Jean was sitting in the school cafeteria with his friends, Marco, Connie, and Sasha. Y/N hadn't turned up yet. She and Jean had separate classes before lunch, so she hadn't been able to walk with him.

'Her teacher's probably let her out late,' Jean thought to himself. He watched as Sasha took a large bite out of a potato she was eating.

Suddenly, a familiar voice rang out from behind them. "Careful, Sasha. Don't choke on that potato."

Jean turned around and smiled as he saw Y/N approaching him and the others. But his smile quickly turned into a frown when he saw who was walking beside his girlfriend. Eren Jaeger. The guy he had hated since he started high school.

As soon as Y/N was close enough, Jean stood up and wrapped an arm around her waist. He glared at Eren with malice and hostility.

"Baby, why are you walking with him?" Jean spat.

"Oh, Eren asked if he could hang around with us for a bit. He told me that Armin and Mikasa are doing something and won't be back until the last five minutes," Y/N answered.

Jean scoffed. "Did you seriously think I'd allow him to hang around us, though? You know I hate him, Y/N. I hate him like I hate most guys that talk to you, except those two," he said, pointing back at Connie and Marco.

"Shut up, horse face. Why can't you just allow Y/N to talk to another guy without insulting them or throwing a punch for once? What's she gonna do? Make out with them?" Eren suddenly spoke up.

Jean felt anger rising within him. He could already feel the urge to kick Eren's ass bubbling.

"You little twat," He hissed. The arm around Y/N's waist tightened. Y/N looked between her boyfriend and Eren. She could feel the tension between the two boys.

"Hey, just stop-" Y/N tried to say, but Eren cut her off.

"No! Jean's an absolute dick. Whenever a guy talks or hangs around you, all they do is get attacked by him, physically and verbally. Remember when he punched Armin in the face and broke his nose because he was jealous? Armin didn't deserve that! All he did was study with you!" Eren said.

Y/N bit her lip. What Eren was saying was true. All Armin did was study with her and his nose had been broken all because Jean had gotten very jealous.

Jean on the other hand, was fuming. He shot Eren a glare that was more intense than before. "I'm her boyfriend! Am I not allowed to be jealous sometimes?"

Eren scowled at Jean. "Jealous?! Sometimes?! Dude, you're basically jealous most of the time! And you express it by insulting someone or hurting them!" He shot back.

Jean was just managing to hold back at this point. He wanted to beat the living shit out of Eren and leave him a bloody mess.

"Y/N is mine! She shouldn't talk to any guys unless I approve of them! Now, can you just shut the hell up and piss off?!" He snapped.

Eren was silent for a moment before he spoke, clear anger in his tone. "You're talking like she's an object or something! She's her own free person! She doesn't belong to you or anyone at all! You're such a possessive and jealous piece of shit! I wonder why she got with a horse like you in the-"

Eren didn't get the chance to finish his sentence. Jean had lunged and tackled him onto the floor. Y/N watched in horror as Jean started beating Eren. She tried to pull him off Eren but he was too strong. A small crowd started to gather around. Some were chanting 'Fight! Fight! Fight!' whilst others watched in slight concern.

Connie, Marco, and Sasha also tried to separate the two, but Eren had grabbed onto Jean and started hitting him back.

Punches, smacks, and a few kicks were thrown everywhere until Jean suddenly stood up and kicked Eren in the face really hard. Blood and even a few teeth went everywhere. He then directed the kicks at other parts of Eren's body, such as the ribs, stomach, etc.

When some teachers finally came, Eren was a very bloody mess. His face was bleeding, bruised, and his mouth was missing a few teeth. He was clutching his side, which was hurting from one of Jean's kicks.

Jean walked towards Y/N and grabbed her wrist. Nobody tried to stop him as they were too busy with Eren. He pulled Y/N away and down into an empty hall. He then pushed her against a wall and pinned her there.

"You're mine, aren't you?" Jean asked.

Y/N shuddered with fear as she gazed into his light brown eyes. "J-Jean, you shouldn't have done that-" She started but was cut off when a hand wrapped around her throat and squeezed slightly.

"Answer the question," Jean said coldly.

Y/N let out a shaky breath before answering. "Y-Yeah, I'm yours."

Jean smiled before pressing a kiss to his quivering girlfriend's cheek. "Good. That's good," He said.
