Annie had been acting strange since you met her. No one noticed except for you. She was always cold and distant with everyone but you persisted, you befriended and loved her and she hated that she let you. However, when she went up to you and said "Run away with me"... You obviously said yes. You never liked the military life, anyway.
As of now, the two of you were camping in the middle of the wood, a good distance away from the training barracks. However, what she says next catches your attention... She was able to shift into a Titan. The Female Titan. The very one you've recently been assigned to hunt down and exterminate... However, you didn't care and loved her just the same. And that's how she knew... You were her one and only.
Now, in your remote cabin where you hide from the Survey Corp and try NOT to be arrested for desertion when you feel the ground shake under you. You go outside, trying to see if you were found by any Titans... Only to see it was simply Annie in her Female Titan form, your large love kneeling down and opening her now massive hand to drop several carcasses of deer, boar, and other animals in front of the house. She seems... rather proud of herself, letting out a few breaths since she can't speak in Titan form.
