Eren Jaeger and Mikasa Ackerman. Both soldiers of which had their own strengths, their own weaknesses, their own flaws, their own things that they stress and worry about.

Mikasa Ackerman in particular had seemed to be worrying about a certain brunette more than usual lately, and she was being rather obvious about it. And of course, the brunette in particular was Eren Jaeger—who was having none of her so-called 'nonsense'.

Recently, after discovering Eren was a titan shifter—and having been reunited with him after the trial, the raven had been overjoyed and relieved at their reunion, but was filled with concern and worry. Such negative feelings came about only because she had assumed they were treating Eren poorly and cruelly, which wasn't the case. The only reason why she would ever make such an assumption would be because after seeing Levi kick Eren ever-so ruthlessly, she didn't exactly expect the other members of his squad to be nice to him.

After their reunion, Eren was allowed to have some freedom and time to his own… a little though—the rest of said time was used for training and experimenting, in preparation for their next expedition outside the walls. And with that little time he was given, he decided to go catch up with his comrades.

However, as he did so, there would always be a certain Ackerman who wouldn't stop pestering and bothering him with her worrisome questions. At first, he didn't mind it much, but lately he found that Mikasa was babying him again, and naturally, he couldn't help but feel agitated. He didn't exactly enjoy being treated like a child, he knew how to stand on his two feet—he knew how to fight… and yet, at least to him, Mikasa didn't seem to be aware of that fact.

And alas, one day, he just couldn't take it anymore.

"Eren, is there something wrong? Is there a problem?Are they treating you fi—"

"What's your problem?" The brunette snapped, in a rather harsh, irritated and cold tone. And in that moment of infuriation, the last thing he felt was regret on what he was about to say next.

Mikasa hesitated for a moment, the angered look he was making… she could already tell what was going on in his brain. She never meant to baby him, she knew she could be… overprotective towards him but she just couldn't help it. She always felt indebted to him ever since that day, that day when he rescued her from those disgusting crooks who had planned to sell her life away to other sorts of revolting crooks. He had given her another chance to live, another 'life'. Not only that, but he also taught her how to fight. Till today, she still remembered the words that he spoke to her. It would always echo about.

'If you lose, you die. If you win, you live. If you don't fight you cannot win.' Those were his words that sparked some sort of flame in her, a flame that could never be extinguished.

"What do you mean—"

"You know exactly what I mean! Stop treating me like a kid! I'm not your little brother or anything!" Eren yelled harshly, causing some eyes from others to fall onto them—having caught their unnecessary attention as the argument continued.

"Eren… I—"

"Shut up for a moment! You're being ridiculous Mikasa! I don't need you protecting me!"

As she heard those words, she remained silent as he had wished, looking away. She could feel the tensed atmosphere that now surrounded them, which only grew in tension as she noticed others staring at them now.

Was she really in the wrong?

She knew she was being a little too worried about the brunette, but she was just scared of losing him again. She recalled that before, she thought Eren had passed away since Armin relayed the news of him having sacrificed his life for the blonde. She held absolute no hatred for the blonde, she would've done the same thing. She wanted to protect those dear to her after all. But when she heard of said news, she felt as if her whole world had shattered before her. Eventually, she managed to pick herself up. One of the reasons was that she remembered Eren's words… to fight, and she knew if she died, she wouldn't be able to remember him.

Thinking about everything now, maybe she was being a little too protective of him recently. 'Am I… just a pest in Eren's eyes?' She thought quietly. There was no denying it, he was right. He wasn't a kid anymore, he had grown, and grown stronger. Upon realizing this, she was about to apologise until Eren had cut her off.

"You're so annoying, I swear. I hate that part of you, so much." Eren spoke coldly.

Immediately, Mikasa looked up as his words echoed in her ears. That he hated that part of her. But which part was it? Was it every part? She didn't know. She probably didn't want to know. But at that moment she felt the same thing about herself. She felt that it was her fault for getting into the mess that she was in currently with the brunette, she shouldn't have been worrying about him so much. She should have minded her own business… she should have backed off of him, then maybe he wouldn't be so mad at her. But she couldn't and didn't, and she knew it was too late to take back her actions.

And before knowing it, tears started to cloud her vision once she met with the brunette's angered emerald orbs. Biting her lip, she finally managed to speak, "I'm… sorry. I-I have to... go…" She mumbled, and before the brunette could say another thing, she turned her back and ran off.

'Ah… I shouldn't have been so… so…' Mikasa couldn't think of any words to describe her protectiveness other than annoying as Eren had mentioned. She was just so relieved he was alive, and safe. But, of course, she was worried for his well-being. After all, he was a titan shifter… and of course, not everyone would accept him for that with welcomed arms, if anything the people back at the trial wanted to dissect him. So, to trust others on ensuring his safety was difficult for her… gaining her trust wasn't easy after all.

As she ran away, she started to reflect on her recent actions. Eren was right, she should loosen up on him a little, she shouldn't be so annoying as he mentioned. She… needed time to reflect, and fix her own flaws and mistakes.

And hopefully, she hoped that Eren wouldn't be so… angry at her like just now.

Meanwhile, the brunette stood there. After she had ran off, and after he had taken a few deep breaths, he immediately regretted his actions. He knew she wanted the best for him, to be safe… he just wished she would let him be independent... he knew he couldn't rely on her forever. He didn't want to be a burden on her. It was just so irritating… or rather, frustrating that she didn't care too much about her own self as compared to him. He wished she would just think about her own well-being… instead of his all the time. But more than anything, he found it so frustrating that—

Before he could go deeper into thought, he felt a grip on his shoulder, turning to see the blonde who apparently witnessed everything.

"Aren't you going to go apologise?" Armin had asked, rhetorically, wearing a little frown. "You know it as well as I do, she didn't mean to be 'annoying' as you said."
