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 glances. Honestly it's no wonder the creeps 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've imagined myself choosing those 2 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
