"To my dear Historia: As I'm writing this, Reiner stands next to me. It's pretty obvious that he's sneaking peeks at this love letter. He can be such a creep. No wonder he's single. However, he did promise me he'd deliver this letter to you. He says it's payback for saving them that one time. I'm sorry about then. I never imagined I would end up choosing them over you. It won't be long till I die. But I have no regrets. That's what I'd like to say, but there is one thing: It's that I wasn't able to marry you. -Ymir."
