Modern Eremin AU: Milestones

Armin's first crush.

Eren sat on the bathroom counter. Armin stood between his knees, holding an ice pack to his black eye and cleaning his cut lip.
"OW!"
"Eren, hold still."

The thirteen year old boys had just gotten home from a day at the park.
Some punks decided to pick on Armin while Eren went to get ice cream.
When the German boy returned, one guy in a snuttie cap and an old hoodie had thrown Armin to the ground, about to kick him. Which then, Eren decided to be superman and come to his rescue... And he didn't exactly come out the man of steel.

Now he was sitting on his bathroom counter with a busted up face and hurt pride.
"Eren..." His blonde friend asked,"... Why did you do that?"
"Do what?" Eren spat.
"Try to take on five guys by yourself."
The outgoing soul stared at Armin like he was speaking some alien language," Because they were bullying you? I mean, come on, dude. What kind of question is that?-Ow."
He winced at the pain shooting through his eye.
The blue eyed blonde scanned his friend's face for any sign that he was kidding," But, you could've really gotten hurt."
"I got a black eye and a busted lip," Eren set the ice pack down, looked him dead in the eye, and smiled his big, goofy grin. "You're my best friend. I'd gladly take a lot worse for you, Armin. And I know you'd do the same for me."
Armin was slightly taken back. Even with his injures, he couldn't help but have his heart skip a beat looking at him.
Eren was like his knight in bruised armor. He didn't care that he got hurt in the process, he wanted to protect him. Armin couldn't help but get giddy at the fact.
He couldn't quiet place what the feeling was, but it spread a warm throughout his body and it didn't want it to stop. He had butterflies in his stomach and his chest tighten.
The blonde boy couldn't help but get lost in his best friend's eyes. They were bright and inviting with a boldness he was tranced by. All the shades of green and blue would've taken decades to count. They were spellbinding.

Eren raised a brow in concern and waved his hand infront of the odd stare off into space from his friend," Uh... Earth to Armin?"
Armin blinked at shook himself out his trance, shooting his gazed to the floor, blushing. "S-Sorry."
Eren held his balled his out to him for a fist bump," You good?"
Armin looked back up at his friend, seeing his smirk and arched brow, almost making him snort at the cockiness of his busted expression. His fist met Eren's and their finger did a finger puppet explosion in retraction.
They both chuckled as Armin went back to cleaning Eren's cut lip, enjoying the close proximity. The Lightning fast beating of his heart letting him know his first crush wasn't going anywhere anytime soon
