Eren and Levi have finally got married and had a baby boy. Their lives were wonderful until one big fight split them apart.

When Hanji experiments on Eren she realises his Titan ability can do the impossible.

****IMPORTANT MESSAGE**** ****I was originally planning on rewriting every bit of this stupid fan fic but I abandoned that thought years ago. I am not going to ever finish rewriting this. I stopped around chapter 2 or 3 so that's where any discrepancies may arise**** ~~~~This is the Prequel to Grown Up Fighters or for some of you, the first book in the series. I am trying to write the second book so you don't have to read one of these first specifically.~~~~ Eren and Levi have been in love for so long it seems. They have been by each others side and have been there when they both needed it. On the most precious expedition, Eren was severely injured but survived due to Levi's sheer determination and Eren's ability to heal himself. But once they get back, Levi never leaves Eren's side. He stays by the bed and is always holding his hand. And with that comes some in expected news that no one would have ever imagined to be possible. DONT JUDGE ME ON THIS BECAUSE I AM GOING TO DO MY BEST!!! IDC OF THE LOGIC IN THE STORY IS BULL CRAP BUT IDC!!!! LET ME WRITE!
