Rivals. It is the word that described their relationship. Their rivalry was intensified when taken to the training area. She despised him; or so she thought.

"Is that the best you can do, (l/n)?" Eren said as the two were in a deadlock, trying to play mercy with each other. They were both trying to push each other out of the circle they created on the floor. "You haven't pushed me an inch in the last two minutes," both of them were sweating under the hot rays of the sun.

"Says a lot about you, Jaeger, You aren't even close to pushing me." She leaned to the side, letting go of his hands, causing him to fly out of the circle. She stood over him and looked at his fallen body. "You can't always push to win, Jaeger. Take that as a lesson." he furrowed his eyebrows in anger and kicked her leg. She fell on her back, stunned by his sudden comeback. Before she could get back up and regain control, he mounted on her and pinned her arms down to the ground.

Her heart skipped a beat. Unsure of the reason, she blamed it on the fact that she lost to Eren. "You already told me that months ago. But here's a lesson: you can't put your guard down, even when you think you've won."

She hatefully rolled her eyes upon hearing his annoying voice. "Titans are nothing. One day I'm going to live outside of these walls and not worry about those pests, Mikasa. Just watch me!" he slammed a hand down onto the table and ate bread from his other- Armin and Mikasa listening patiently.

That was the last straw for her.

"ugh," she sighed and walked away, wanting to escape his annoying voice.

It was his impulsivity and lack of restraint that she didn't like the most. He would get killed one day as a result of his absence of self control. This is important especially because he was a titan. And it was also because of his abilities to turn into a titan that she hated him. Everyone gives him praise and attention for being something the humans are trying to eradicate.

She heard Jean making a rebuttal to him but she didn't bother to listen; it was probably too stupid for her anyway. She didn't like him either, he was too similar to Eren- which would explain why they never get along. Jean paused as he saw her heading to the door and ran for her.

"Hey, hey, where are you going?" he grinned cockily, blocking her path at the door.

"I was about to go kick someone's ass because they wouldn't let me through the door." she snapped at him which caused him to turn red in embarrassment, and Eren to erupt into laughter behind her.

"Shut up, Jaeger!" Jean shouted, "It's not like she would like you more, anyway!"

"Oh yeah? We'll just see!" Eren shouted back to him.

"Boys, boys, no need to fight over me. I hate you both equally." she replied, walking out of the door. Both froze at her response.

She walked to a table in front of the main building and just watched the other soldiers laugh with each other.

"I didn't know you hated me," A voice said behind her. She turned around- Eren had followed behind her. "I mean, yeah we're rivals, but I didn't think you hated me. I thought his was just all fun and games." he said and sat down beside her. "Why do you hate me?"

"Piss off, Jaeger." she said, getting up from her seat and walking away to start training again. She can't even stand to breathe the same air as his. He grabbed for her arm but immediately pulled back.

---

"(y/n), just tell me," Eren pleaded as they sparred with each other.

"No." she coldly replied, "why do you care? Jean doesn't care if I said I hated him."

"Because," he became vulnerable, which she took as an advantage to punch him square in the stomach, causing him to fall to the ground, doubled over and clenching the area she hit.

She held out a hand to help him up and left as soon as he was able to regain his composure, leaving him with his unanswered question.

---

She cleaned the girls rooms along with Christa the day after, as per requested by the captain.

"(y/n), can I ask you a question?" Christa asked, spreading the bedsheets across the mattress.

"Sure thing," she replied.

"Why do you hate Eren?" (y/n) squinted her eyes as soon as she knew where this was going.

"I hate him?" she asked.

---

"Why do you hate Eren?" Connie asked as they sparred together.

"That's funny, Christa just asked me that yesterday." she laughed. This was all part of Eren's plan. Typical.

"Really? So can you tell me why you do?" he asked eagerly.

"No," she replied, kicking him straight in the leg.

---

"Hey, (y/n)!" Armin called out to her in the training area.

"Hi Armin!" she waved at him as he sat down beside her. "What's up with you?"

"W-well, I was taking a s-survey right, and uhm it's a survey on whether people like or dislike... Eren and w-why." He trembled. She knew he couldn't lie to a friend.

"Alright, I get it," she got up from the table, started walking off.

"W-wait!" Armin called, she turned back to Armin.

"Armin, you don't have to work for him anymore, it's okay." she stated.

"Where are you going?" he pursed his lips, hoping that this doesn't turn out into a war.

---

"Hey, you." she called Eren as he was talking to a bunch of other soldiers. "I want to have a chat." She grabbed onto his arm and pulled him away to wherever it was quiet.

"Ow!" Eren complained.

Both eventually ended up talking behind the main building. She pushed him against the wall.

"Really? You would go as far as to making Armin lie to me so you can find out why I don't like you?" she unconsciously balled her hands into a fist.

"What?" he raised an eyebrow at her.

"Fine. Fine. You want to know why I hate you?"

"Why?" as much as he wanted to hear it, he was almost scared. All those months of specifically making her his rival will amount to them eventually not speaking to each other.

"You have no self-restraint, everyone praises you when we are fully in par in combat and when actually using the gear, too impulsive, and have a short temper." she paused and looked to the side crossing her arms, "You're gonna get yourself killed one day because you can't control your need to carry out your desires, despite how dangerous they are. Sometimes you have to think about yourself, Eren. You can't be too selfless. Don't be an idiot."

Eren looked at her, "Why are you telling me this suddenly?"

"You kept pestering me for the last few days! And because, like I said, you can't always push to win, Eren. You have to hold back sometimes." she replied, still not looking at him.

"No, no." he shook his head and flicked a hand, "The second part- you're giving me advice, why? I thought you hated me. Unless... you actually care about me? Hate so deep it's love, amiright?" he grinned and wiggled an eyebrow.

She flinched, "You're delusional Jaeger!" she looked away, blushing and furrowing her eyebrows. She denied all thoughts of her actually liking him. It was out of the question. "I'm just teaching you a lesson! Why can't you just take it as it is?" she retorted.

"I'll take it as a lesson when you stop blushing," he put his hand on top of hers and leaned forward to meet her gaze "okay, (y/n)?"

"You fucking-" she was ready to strike him across the face with her other hand and he immediately stopped it.

"Is that the best you can do, (y/n)?" she trembled and put her hand down, angrily looking at him. "I have been holding back for a while now actually. I haven't made advances on you, and made you my rival so I had a reason to talk to you. I know you don't hate me, (y/n). I know you hate Jean though..." he smiled at her, cupping her cheeks. She was speechless, her face turning red at the feeling of his warm hands on her face.

She looked away. He leaned in closer and gave her a chaste kiss. She returned it grabbing his collar, intensifying the kiss and catching him off guard. She felt him grin under the kiss as soon as she pulled him closer, feeling his warm breath trail on her lips. He kissed her bottom lip just before they parted, catching their breaths.

"Well," he blushed, looking off to the side.

"There you are!" Armin said, their heads shot towards his direction. "Eren, sorry. I couldn't do what you said, but please don't fight!"

"It's okay, Armin." he said.

"Is that the best you can do, Jaeger?" she grabbed him by the shirt, their faces inches apart. Armin halted at the side, ready to stop the oncoming fight.

"Please don't!" Armin cried out.

"I'll show you my best tonight," he whispered to her, grinning.

She let go of his collar and walked off. "I'll be the judge of that, Jaeger."
