This is an attack on titan, Ereri (Eren x Levi) fanfiction

Humanity's strongest, at his weakest

It had happened so suddenly. One minute he and Levi were swinging through the trees using their 3DMG, then next, a titan burst out from the trees. Levi slammed right into it and fell to the ground with a thud, unmoving. Eren reacted quickly, and swung down to pick him up and fly back up to a tree branch out of the titan's reach. The titan was killed with a quick deep slash to the nape of the neck. The titan was gone but Levi was unconscious. Luckily they weren't far from the camp. Eren fired off 3 lime green flames in a row to signal that someone was injured.
"Levi if you can hear me, everything will be ok," Eren spoke in a worrisome tone.

Just then a yellow flame was signaled and the sound of hooves became louder. Eren picked up Levi bride style and zipped to the ground.
"We received your signal!" Jean said
"We came as fast as we could!" exclaimed Armin.
"What happened here?" Asked Mikasa
"What happened to Shorty?" Hanji asked smirking at her witty comment.
Eren explained what happened and then worked with the others to lift Levi into the cart. Once Levi was secured in the cart, Eren climbed in and sat next to Levi in the way back.
Eren couldn't believe what had just happened, Levi was usually so careful. Eren hugged his knees to his chest and tears filled his eyes.

After they got to the infirmary they brought Levi in to fix him up. Eren waiting outside all day until he was allowed to enter the room.
In the room Levi lay on a bed, asleep. He was wearing an oxygen mask to ensure he was breathing correctly, and a bunch of wires were attached to his chest and arms.

Eren lay his hand atop of Levi's. Levi stirred in his sleep and fluttered his eyes open, seeing Eren, he smiled.
"Hi" Levi said. He tried to sit up but gripped the side of his head and lay back down.
"Don't try to sit up Levi, just stay still," Eren said as he sat on the bed. He nodded and for once he wasn't the one giving orders. Silence filled the room as the males got lost in each other's eyes.
Eren removed Levi's oxygen mask and leaned closer to him so that their lips were only millimeters apart. "Eren?" Levi whispered. "Corporal," Eren responded before gently placing his lips on Levi's.
