To my dear Historia, As I write this Reiner is standing at my side. He knows this is a love letter but he's still sneaking peeks. Honestly it's no wonder the creep is still single. That said, he did give me his word that he'd deliver this letter to you. He says he owes me for the time I doubled back to save him.
I'm sorry about that. I never would have imagined myself choosing those two over you. I'm going to die soon, but I'll die without regrets...Or that's what I'd like to say. Truth is, I do have one. It's that
I never got to marry you...

With love, Ymir.
