(I don't own Shingeki no Kyojin. ouo)
Eren spent the next two weeks doing exactly as he had planned.
He ran extra after school, added a little more to his lifting regimen, mainly based on his legs, but not completely focused.
Mikasa, his adoptive sister, sat next to the track as she watched Eren go lap after lap of running. The whole way, she could tell, the flame of determination hadn't even waned a bit. She then decided to speak up after the fifth lap.
"You've done a good mile, Eren... shouldn't you stop?" She recieved her answer by the expression she got from him. She audibly sighed and spoke again.
"At least take a little break, Eren. If you want to beat him, you can't over-exhaust yourself, alright?" Eren seemed to take the little note to heart, and nodded. He slowed to a stop once he rounded the curve, and met her at the finish line in a slow jog.
Mikasa handed him his water bottle with a smile, and gave him a rag to wipe the sweat off his forehead. He nodded his thanks and drained the bottle before wiping away the persperation gathering and dripping down his face.
"You'll beat him someday, Eren." Mikasa said, in hopes of cheering him on. He smiled back at her, eyes shining with the same determination they always held.
"Thanks, Mikasa. I'll get him this time." He clenched his fist in excitement.
The next meet would be in two days, and he was trying not to over-exert himself, but Mikasa was right. He had run a lot more than he was meaning to in the beginning. Today was different, but only for the fact that Mikasa had stopped him, and reasoned with him.
Even so, Eren always went all-out.
"You know what, I think I will go home." He made the move to grab his things, but was stopped by Mikasa.
"Stretch first. You don't want to wake up tomorrow with knots everywhere."
Eren facepalm'd for forgetting this. "Right, thanks for reminding me, Mikasa." She simply nodded and grabbed his things for him.
He took a good five minutes to stretch before standing up, cracking his back, and taking his things from Mikasa with a 'Thank you.'.
They walked home, the sun setting. It seemed to soon for it to, though. The two didn't mind.
In an attempt to break the awkward silence, Eren was going to speak up, when Mikasa spoke first without hesitation. "What's he like, Eren? Do you know very much about him yet?"
"... Actually, I don't know very much about him, because I only spoke to him for a few seconds and all; he seems slightly rude.. but I'm sure that's not all to him! He's runs like... like..." Eren started making hand motions to try to express how fast Levi was.
"Like a cheetah, or something! It was great!"
From then on, Eren began babbling about how well he ran, how he made the starting block look so cool, all with a tinge of pink dusting his tanned cheeks.
In the orange light, Eren looked beautiful to Mikasa. Though, she knew that he only thought of her as a sister, and the way he talked about Levi caused a twinge of jealousy to twinge in her heart. She wouldn't ever let anyone know, though.
She was happy that he found a rival, and she knew that if the two conversed and hung out enough, that he would probably go farther with Levi than just 'friends'.
Eren WAS, in fact, bi. Mikasa knew this.
And Mikasa knew that in time, Eren wouldn't be hers anymore. He would be able to live on his own.
But Mikasa would only be proud.
Though Eren didn't tell anything about his feelings toward Levi yet, and that they were of simple admiration, one thing crossed her mind.
Take care of Eren, Levi.
