Clarity -Ereri- -one shot-

High dive into frozen waves where the past comes back to life,
Levi looked over when he heard the loud scream. That voice…Don’t tell me... Levi’s eyes widened as he swung over to the direction he heard his lover’s cry. How could the plan have failed this much? He was supposed to trust his comrades!
Fight fear for the selfish pain, it was worth it every time,
Eren had to be okay. That was what Levi had to keep telling himself. The first one he found was Guther. Levi’s heart dropped. No. This couldn’t be right. He kept going. This couldn’t be right. This wasn’t how things were supposed to go. Erd was the next one Levi came to and reality started hitting. He had to go faster. He had to get to Eren. He had to save him before… before whatever was happening ended him. That fucking bitch wouldn’t dare hurt him! Levi’s facial expression grew grim as he started mourning over his friend’s deaths. He was supposed to protect him. He failed. Oluo was next and Levi couldn’t take it. He need to get to Eren. He had to make sure he was okay. He had to keep going and make this a success. For his friends.
Hold still right before we crash 'cause we both know how this ends,
Levi stopped and stared in disbelief. No. This wasn’t right at all. She wasn’t supposed to die. She wasn’t… she couldn’t. Petra was the one person Levi let in besides Eren. She couldn’t be dead… but here he was standing in the tree Petra was crushed against. Revenge was in order. He craved it at that moment. He held back his tears making sure he didn’t reveal any of his emotions. He was on the job. His heart hurt though. Everyone was supposed to come back alive. They never did. This was always how it ended. In war sacrifices are always made. Eren…
A clock ticks 'til it breaks your glass and I drown in you again,
Levi started to fly faster when Eren’s yelling stopped. Something was wrong. Something was terribly wrong. Eren had to be okay though. He had to be. Levi repressed his feelings further. “Tch. I’ve already lost too many for this bitch to get away. She is not getting my Eren too!” He swung and noticed Mikasa going after her. He grabbed her by the waist and swung her away from the Female Titan. He kept eye contact with her to give her, her orders. “Fall back for now.”
“Tch…” Mikasa let out as she looked away from him and stared at the escaping titan.
Levi made sure they didn’t get too close as he let Mikasa go. They were going to get Eren back. He would make sure of it. “Maintain this distance. It may be tired. It doesn’t appear to be going very fast. He seems to have been bit right out of the neck. Is Eren dead?” And if it was tired, Levi would be damned if he just let it escape with his lover. He had to get him back in his arms. He had to make sure Eren wasn’t going to go out like this. He had to save him before he ended up like the others. He needed Eren in his life.
'Cause you are the piece of me I wish I didn't need,
Mikasa looked over at him and then back ahead of her with determination. “He’s alive. The target appears to be intelligent, and its goal seems to be capturing Eren. If it wanted him dead, it would’ve crushed him. The target is fighting to escape after going through the trouble of putting him in its mouth.”
Levi thought that could be a possibility, but he had to take in everything. If Eren was dead he didn’t want to go after the titan. Eren wouldn’t want that. He’d want Levi to keep fighting. Levi had to put his feelings aside for this one person. “Its goal may have been to eat Eren. If that’s the case, he’s in its stomach. It’s more reasonable to assume he’s dead.” He couldn’t help the affection that went through with the name. Eren hadn’t told Mikasa about their relationship yet, but at this point Levi didn’t care. He had to get to Eren. He had to make sure he was okay. He had to make sure that Eren was alive and breathing in its mouth. It hurt to say all that, but someone had to say it and since he was a “heartless asshole” he may as well be the one.
“He’s alive!” She shouted staring up ahead.
Levi looked at her, “I hope your right,” he whispered before sighing and looking away. He was worried sick. That much was true. He felt sick to his stomach just thinking about how Eren could be in that filthy mouth or stomach. He would have to bathe him for weeks and, of course, shower him with enough love and affection until the next mission.
Chasing relentlessly, still fight and I don't know why,
Then she said the one thing that broke his heart. The one thing he had been repressing in his mind to keep going. She said it.
“If you’d only protect Eren, this wouldn’t have happened!”
Levi looked over at her in shock. He didn’t want this to be happening anymore. He whipped around to face her. “I see… you’re the one from back then. Eren’s close friend?” He said though he already knew who she was. He heard a lot about her from Eren, and from what he heard, he could tell he wouldn’t enjoy her presence in Eren’s life. He decided to change the subject before they started fighting. “We’ll limit ourselves to a single goal. First, give up on killing the Female Titan.” He hated saying it. It had killed so many and now it was going to try and use Eren.
“It killed many of our comrades!”
Levi’s face turned grim as his lips thinned. He had to make the choices he’d regret the least. He had to be the smart one in this before they were both killed. “As long as it can harden it’s skin, we can’t kill it. Do as I say. We’ll pin our hopes on Eren still being alive, and rescue him before it leaves the forest. I will tear away at it… you draw its attention!” Levi got out his swords, watching as Mikasa went to the front of the Female Titan and drew its attention. At that moment, revenge went through Levi. This was for Eren.
If our love is tragedy, why are you my remedy?
Their love had made him stronger. Their love was the reason he was fighting. It wasn’t just his comrades’ revenge. This was for Eren. Eren, who was his lover. Eren, who was always fucking there when he needed him. Eren who wanted to kill all the titans while wearing that shit eating grin of his. Levi got level with the female titan’s neck and waited. He knew she had seen him. She turned around and swung a punch, but Levi was ready and spun up her arm cutting across it. He stopped and jumped up to blind her. He then jumped off her face, reloaded his swords and went at her again. Eren had to be safe. He had to at least try. He had to get back what he needed most in his life. He let out a cry and spun down her body making sure to hit her weak points. This was what the bitch deserved for making him suffer like this. For eating Eren. With a final hit to the back of the head she collapsed with her hand over her neck. He kept attacking her. Hitting all her points. Making sure to hit her tendons before she could harden. He kept his mind on Eren being alive. He kept remembering all the times he held the boy, took the boy, made him cry thousands of “I love you”s, and the smile he would give after. Their love was so intimate. So strong. So addictive. Levi couldn’t lose it yet. Eren was alive. He had to be.
Her arm fell.
If our love’s insanity, why are you my clarity?
Levi heard her wire attach to the titan. His eyes widened. He knew it was too soon. This wasn’t the plan. “STOP!” He quickly swung to her when the Female Titan’s hand rose and pushed her out of the way. He landed on her hand wrong; his ankle twisting. “ACK!” He tried not to cry out in pain. He had to act fast. Now that he was wounded he needed to get out of there before more trouble came. Before Mikasa did anything else that was stupid. He jumped off her hand and sliced through her jaw, praying Eren was just in her mouth.  He watched the mouth open.
“EREN!” Mikasa cried going for him.
No. This bitch was not going after the love of his life. Levi swung forward and grabbed Eren then landed on a branch. “Hey! We’re getting out of here!”
“Eren…”
Levi held him in one hand looking down at his spit covered boyfriend. He would really need to bathe him. “I think he’s okay…He’s alive! But filthy…Forget about it. We’ll retreat. Don’t lose sight of the core objective. Is it more important to get what you want? Isn’t he an important friend?” Levi could feel the blood evaporate from his face and it disgusted him. He could feel the saliva going down his arm, but he didn’t care. His boyfriend was in his arm, warm, protected and alive. Just unconscious. Levi turned and swung away from the Female Titan. Once he was far off he turned and saw that the female titan was crying. He was shocked.
If our love is tragedy, why are you my remedy?
He stopped and looked down at Eren’s unconscious body and moved him to be carried like a bride. He leaned down and kissed him. “I saved you. Rest easy now.”
“Captain… I would rather you not defile his body while he’s asleep. Eren hates you.” Mikasa hissed as she came up behind him.
Levi glared over at her. “We’ve been dating for some time now so don’t you dare say he hates me, brat. If it was up to you, he would be dead right now! So don’t patronize me! I almost lost the love of my life today!” Levi stared at Eren and broke down. How could he confess that to someone other than Eren? He normally wasn’t such a wreck. Eren had scared him. He really thought Eren was going to die. He held the boy closer and nuzzled his wet chest. He fell to his knees and held Eren tightly shaking as he let his tears fall. His ankle hurt. His heart hurt. He just wanted to be home.
If our love's insanity, why are you my clarity?
A hand went up to his cheek. “Please don’t cry, Heichou… not over me.”
He looked over and saw weak emeralds staring up at him with a small smile. “Eren… Don’t you dare do that. Don’t you dare scare me ever again. Do you hear me?! That’s an order!”
Eren smiled and nodded. “Yes, sir. We’ve made it through our first mission being together, Levi.” Eren nuzzled his shoulder as he talked and rubbed his thumb over Levi’s cheek.
“Eren!” Mikasa shouted as she tried to take Eren away from Levi, but Eren just clung on to the corporal more.
“Mikasa… let Levi hold me.” He whispered softly as he wrapped his arms around Levi’s neck and sat up hissing. “Levi, I love you.”
“I love you too. So much.” He whispered staring down at the boy, ignoring his sister. Eren was taking his worries and regrets away. Eren had made it back. It was a selfish thing to want. Everyone died to protect Eren and here Levi was being so grateful that he could hold this being in his hands. He was still sad about his comrades’ deaths, but so thankful that they had followed his orders to their dying breath.
Walk on through a red parade and refuse to make amends,
Once home, he was put under being a liability and unable to work. Eren was assigned to take care of him but the people were outraged. They’d have a lot of shit to pull to be able to do the next mission. Levi felt that something big was going to happen. Like a bloodbath or something. It didn’t matter though. Eren was with the survey corps still.
It cuts deep through our ground, and makes us forget all common sense,
“I’m sorry, captain… I couldn’t save the others.”
“Yeah, well, neither could I and I’m Humanity’s Strongest so it makes us even.” I sighed sipping my tea while resting on my bed, foot bandaged and elevated.
“Yeah… but it was my responsibility.”
“Eren, don’t blame yourself. That’s just part of the job. Dying… is inevitable. Sacrificing everything is our job. There’s nothing we can do about it until the last titan has fallen. Just aim for that goal and you’ll avenge all of them.”
“I still feel bad.”
“Don’t it’s not your fault.”
“But it is! If I hadn’t been a titan shifter none of this would have happened!”
“If you weren’t a titan shifter we would be making zero fucking progress! We would have all died because everyone fucking knows that we would have lost by now if it wasn’t for your fucking powers! Stop being a brat and grow up already! Time sucks but there’s nothing you can do!”
Don’t speak as I try to leave because we both know what we’ll choose,
Levi watched Eren get off the bed next to him and walk out. Whatever. Let the brat go cry to Hanji or whoever has the fucking misfortune to running into him. Levi felt cold and hurt.
If you pull then I’ll push too deep and I’ll fall right back to you,
Three days later, Eren came back in and saluted. “… Corporal… I’m sorry for my outbursts. I-”
“Save it. Just save it, kid… come here…” Levi turned in his chair and held out his arms. Eren walked over and stood close. Levi pulled him down in his lap. “I’m sorry I yelled. I hadn’t meant to. I shouldn’t have. This all sucks and-”
“Corporal, I want to kiss you.”
Cause you are the piece of me, I wish I didn’t need
Levi closed his lips as he stared up at Eren. Was he really fucking serious? He sighed and nodded. “Fine. Whatever. Go ahead.” Levi had given in. He had given in because he didn’t know how many more kisses Eren had left to give. He didn’t know when a titan would pick either one of them up and pop them in their mouths.
Chasing relentlessly, still fight and I don’t know why
Eren leaned down and kissed him before leaning away and walking out.
No. This wasn’t going to happen. That was the shittiest goodbye kiss ever. Levi stood and started running, not even giving a fuck about his ankle that he could tear. He just wanted Eren to be close again. He chased him. All the way into his room- not the dungeon.
If our love is tragedy, why are you my remedy? If our love’s insanity, why are you my clarity?
Levi was locked out. He started beating on the door trying to melt holes in it with his glare. “Let me in, brat. I need to fucking talk to you.”
“… I love you, Levi.”
That didn’t sound like Eren. That… sounded… like a person with regret. No.
“Eren, you little shit, get out here, now. You’re going to do something stupid!”
“…Goodbye, Corporal.”
“Eren! Fuck… I love you, kid. I can’t love you if you’re going to be fucking ashes. Get the fuck out here, let’s talk about this. What about avenging your mother?! What about killing all the titans!? What about marrying me and doing all that stupid ass couple shit?! Get out here!” He was in the damn hallway pleading for a door to be open. Screaming at his loved one.
Why are you my clarity?
If there was going to be one thing Levi regretted his whole it would be not stopping Eren from walking out of his room three days ago.
Why are you my remedy?
Levi sank to his knees as he began to cry for the first time over someone. “Please… at least explain what you’re going to do.”
“… I realized something, Levi. I realized that even if I try so hard… I can’t protect the people I love. I can’t even protect you from seeing your most treasured family dead… I’m a burden to humanity… and I get everyone thinks I’m humanity’s last hope… but that’s just not who I am. I’m just Eren… I’m just… a kid who was way over his head. I wanted to be mature at least once in my life and this is the best option for humanity. So… that’s why… I barrowed a gun from the underground’s black market.”
“Eren… fuck… kid… you’re going to crush me if you do this! Don’t you understand that?! I can’t get over them! I can get over anyone, but you! Don’t do this…”
“… I have to…”
“No is forcing you to put a fucking gun to your head! Just come out here and let me fucking hold you and calm you the fuck down! I love you too damn much to let you give up on yourself! We’ve all made mistakes, Eren! I made a huge ass mistake that caused my closest friends to die! If the Corps can forgive me for that then they can forgive you too! You made a wrong decision but so have I! Just fucking come out!”
Why are you my clarity?
The door unlocked.
Why are you my remedy?
Levi sighed and walked in and held Eren close, putting the gun to the side. He pressed him into the bed and held him close, letting him cry in his chest. He rubbed his back and sighed. “Don’t you ever fucking do that again. You can kill the whole human race and I will still expect you to live on without regretting it. Your life is so damn important to me, Eren. Even if we’re the last people on this god forsaken planet I will be the happiest guy alive. Don’t give up on our future.”
“… Okay… I’m sorry, Levi… I just… I…” Eren broke off and cried more. “They died because of me…”
“They died because of the titans.”
“But-”
“They wanted to prove to you that they could do it and you let them. You let them have their wish. That’s all they could ever ask for. You /trusted/ them and me.”
Eren looked down and nodded. “Okay…”
“Okay.” Levi sighed and rubbed his back.
If our love is tragedy, why are you my remedy? If our love’s insanity, why are you my clarity?
After that, they both lived a life of no regrets. A life with each other watching their comrades die for their future. They were determined to get to the other side of those walls. They wanted to see the whole world. That was their goal. That was their future. And they would achieve it.
