It doesn't matter if you are in school, college, work or even in the military, there is always that couple that no one can decide what kind of relationship they have.
The 104th Trainee Squad was no exception to this, since Eren and Mikasa's relationship was always subject of disscution.
Some say they are like siblings (they lived together for a year, after all).
Others say they are just best friends (since they are always together, but have never been seen holding hands or anything).
Most are betting when they are getting together (it was just a matter of time).
And that, of course, meant pushing their limits just to win.
"Beautiful flower for a beautiful lady" Reiner Braun, in all his ripped glory, smiled while offering a flower to the Asian beauty at his side.
"Thank you, Reiner" she took the flower, blushing slightly when he winked at her.
His smile got wider when he noticed Eren's clenched teeth.
"You are mine, you hear me?" he whispers in the night, his face in her neck as she only hums to answer "Only mine. No one else's"
"Mikasa!" Jean's voice sounded some meters away from Mikasa, Armin and Eren. He was running, trying to catch up with them. "Mikasa, you left your book!" Just as he said, a red book was on his hand, 'M. Ackerman' written on its cover.
"Oh, thank you, Jean" she took it from him, giving a nod. "I'm usually more careful"
"Oh, it's no problem at all. I'm always here to help. Just call if you need anything" he sent her a smirk and left with his hands on his pants.
"I'm surprised he didn't stutter" Armin commented to Mikasa, ignoring Eren who was frowning and rolled his eyes at his friend.
"If we told people about us, we wouldn't be having this conversation!"
"Mikasa, c'mon, it's not that!"
"No, Eren! Before being yours, I am my own person, so I won't stop talking to people just because you feel like I have to be only with you! I can have, and I will have male friends"
"Mikas-"
"No! If you trusted me, you would realize that there is no one else. Never have, never will"
"You do realize that you brought this upon yourself, right?" Armin raised an eyebrow to his friend, trying not to laugh.
Because obviously Eren Jaeger trying to kill Marco Bodt with his eyes was hilarious.
"-If only you told people you're dating-"
Marco Bodt, who was talking to Mikasa.
"Everything would be simple, no one would-"
Marco Bodt, who was leaning to point something-leaning close enough to-
"THAT'S IT!" he yelled, stood up and slammed his palms on the table "You!" he pointed Marco "Stay away from Mikasa, you hear me?"
"Eren" Mikasa warned, looking at him with wide eyes, trying to get him to shut up before he said something he would later regret.
"That is my girlfriend, so you better not try anything! Y'ALL HEAR ME?" he turned to see the rest of the class, narrowing his eyes at them.
"Mister Jaeger, if you would please sit down so we can continue with our class?"
"Yes, sir" he sat and looked down, a faint blush coloring his and Mikasa's cheeks.
"Thanks, man. You made me richer" Armin murmured, looking at Jean and Connie.
A few seats away, Reiner extended his hand with his palm up to Connie.
"Pay up" he whispered, grinning like an idiot.
"Thank you, Mikasa!" Sasha told her in a hushed voice from the seat behind "If you waited another week Jean would have won! I'll give you half of his bread tonight at dinner!"
No one tried to get too close with Mikasa again. Not after Eren almost bit off the head of the last guy that tried after Marco.
(Who was actually trying to help Jean win)
