Huh, well that's a lot of words and overexaggerations to describe their relationship. Byleth cares about Dimitri, certainly, and he has always sought him out to make sure he's all right during their free time around the monastery- but maybe Dimitri thought more of those little chats than Byleth did, and for that Byleth feels a bit guilty.

He nods. "Yes, as long as I am here, I want to do all that I can as well."

His eyebrows knit together, a bit worried. "But I do not want you to lose yourself, either. I can't truly understand what you went through, but please... I don't want to see you become unlike yourself again."
