This takes place when Mikasa and Eren are 20 and there are no more Titans in this story.

Eren's PoV
Mikasa is always trying to protect me, I'm not her little brother! Why can't she see that! Well, our relationship doesn't make me feel like that. When I'm around her I get nervous about screwing up, I worry about looking weak, and I feel like I should, no, I need to protect her. I cover it up with arrogance and anger but I know it won't work forever. Are you supposed to be feeling like this about your (kinda adopted) sister? Is this family love or something else? I'm so confused. I need to know. I'll find out tomorrow.

Mikasa's PoV
I know Eren gets mad at me for trying to protect him but he doesn't see why I'm doing it. He's my light, he gives me life. Without him my world is gone, he is my sturdy rock and I need him to keep me steady. He's the reason I keep fighting. Like he told me all those years ago. "Fight. You must fight. If you win, you live. If you lose, you die. If you don't fight, you can't win." Without him, I'm lost. Why can't he see that by protecting him, I stay strong. I can't live without him. I love him. One day I'll tell him, one day.

Eren PoV
I see Mikasa the next and I walk up to her. "Hey Mikasa you want to up to the tree spot where we were on the day of the fall of Maria?"
"I suppose so, why not?"
"Let's leave in a hour."
"It's a date"
"Okay!"
A date. That word makes my heart soar like using 3D Omnidirectional Maneuver Gear in the air.
But why?
