Sometimes I think I want to kill you

Yuhi doesn't bother glancing over her way, knowing what sort of expression she's pulling right now. 

His gaze remained fixed on the ocean as the snow continued to fall heavily, "Just like a little kid, how childish my behavior is. A brief declaration on a plain piece of paper. Relying on such things to keep our relationship together renders everything worthless and empty." 

To propose for such a reason, he knows now that he's told her the reason she will feel nothing but guilt now. He doesn't want to see that expression on her face anymore; he doesn't want to be the reason why she's suffering.
