Guess the song inspiration used for this.
Warning does not follow up with the official Attack on Titan story line. Another warning this one shot will be extremely gorey. Technically spoilers if you don't know who the female Titan is but I don't really mention it much.

No one's POV:
After the discovery of Eren Yeager and Y/n L/n being Titan shifters and after their trials. They were sent to the Levi squad both of them. They were forced to go through a series of training procedures to prove themselves.

Y/n L/n didn't have the same problem as Eren when transforming into her Titan the procedures proved. Her titans name was a strange one, it was named the Cannibal Titan. The reason for was many eye witnesses had seen her Titan form use it's mouth the most, yes it did use the human fighting skills like Erens. Nobody else had noticed one thing, how extremely bloodthirsty her Titan form had become as time went on when she was in that form.

Eventually one time had Y/n woken up in the her own bed with so much blood on her and a bunch of bandages. It confused her bit how she got back to her bed in the scout base. She didn't remember how she got back, all she knew was the female Titan grabbed her and placed her in her mouth. She blacked out because of the warmth and extremely hot saliva.

It had warmed her up so much she couldn't stay awake for long it felt extremely weird being inside the female Titans mouth. Just before she was placed into the female Titans mouth she had seen Erens eyes widen in the corner of her pupils and how he had reached out for the h/c girl. Eren became furious that the female Titan had taken the one other person he loved dearly. He didn't know if she was completely safe but he didn't want the female Titan to leave with her.

What Eren nor the others knew was the female titan knew how to win Erens attention that's why she did it. Simply take the one person he wouldn't bare to separate with and keep her with them. It was a plus factor that the same female was a Titan shifters like the rest of Annie's group.

"Y/n!!!!" Eren yelled out in an almost desperate tone while his eyes widened at what had happened. The female Titan had placed his crush into her disgusting mouth. Eren quickly used his gear to get closer while biting his hand in anger. Which caused him to transform into forming his Titan form.

The rest was just a massive fight between the female Titan and Eren for Y/n. In the end Eren was also taken hostage by the female Titan but before he passed out, he quickly grabbed and held onto Y/n. Since both of them were stuck inside the female Titans mouth. After Mikasa and Levi had taken back both Eren and Y/n they went onto the high tree branches. The reason was because the female Titan had screamed out loudly causing a bunch of other Titans to come and start to eat her.

The real reason Y/n was a Titan shifter was unknown but her Titan name had another worse truth to it. A while ago a Titan was seen devouring another small and weaker Titan by it's flesh. That incident had been pushed off as a Titan shifter but it was far too late to save them or check to make sure.

Nobody was told though when Y/ns Titan form went on a small rampage of eating her fellow scouts. Of course she had known none of them when the Titan form did this. She couldn't help but still feel guilty for letting her Titan form go that low. She remembered all their deaths and  screams so vividly it almost haunted her.

That's one secret she'd take to the grave with her whenever she would die that is. Since her Titan abilities basically stopped her from dying like a normal human would have. She wanted nobody to know she had a Titan form that ate other humans and Titans on occasions. She would have been killed even for being a shifter when they found out. So she couldn't risk this secret getting.

Back to Eren and Y/n who were currently back at the scout base. Eren had woken up after a couple hours and Y/n had already been up. The moment Eren got up the only thought in his mind was 'Is Y/n ok?!' with that very thought he went looking. He quickly got up and went searching for his crush only to find out she's in her room.

Eren nervously knocked on her door and heard her angelic voice say 'come in' but it sounded weak. She must have been tired from that female Titan trying to take both her and Eren to wall Maria knows where. He entered only to be slightly worried cause he saw Y/n was sitting up and looking back at him. She gave off a weak smile while having a couple of bandages on her body which were covered in some blood.

He walked over and nervously sat on her bed after being beckoned over by Y/n weakly. Eren gently grabbed Y/ns hand and kissed it while holding onto it.

"I-i thought I lost you for a moment!" Erens voice said while he was trying not to cry in front of his crush. He hated the idea of being seen weak in front of his favorite person. Instead of a reaction he was expecting he simply got Y/n gently grabbing his head and placing it right above her chest.

"It's ok Eren, you know I wouldn't die that easily...not when I love you so much" the female Titan shifter says while smiling. She knew she basically just confessed but she wanted Eren to smile. Eren felt his cheeks go a bright red and he glanced up at Y/ns smiling and he gives a smile back.

Whenever he saw Y/n smiling his sadness and other bad emotions went away like magic. Eren gently pulls away and cups Y/ns cheeks and suddenly kissed her on the lips gently. He didn't wanna ever lose his crush again after hearing her basically confess to him.

Y/n was completely stiff at first but then slowly kisses back while wrapping her arms around Erens neck. They continued to kiss for a few minutes until they both needed the dreadful thing called air. They parted and both blushed at each other but smiled at the same time. The two Titan shifters lay onto Y/ns bed and cuddle while smiling.

Both of them were in a comfortable bliss nobody could ruin it for them just yet. Well unless you count Levi and Hange coming to check on where they went and stay quiet. So for now both of them laid in complete happiness while looking into each other's eyes.
  
 
They were now a completely happy couple even if they hadn't spoke the words. They both knew the other loved them until the end.
 
 
  
  
  
Please don't take what I say as the wrong way I just get annoyed if someone tries to correct my grammar mistakes and errors when all I'm doing is writing for fun.
