“She was so pleased I was eating at all…” And Hiei does, despite all of his huffing and puffing, like to keep Yukina happy. It’s been different, surrounding the point of Kurama and their former-and-still-continuing relationship recently, but if he can appease her by eating, why not?

Obviously this is his answer, but still.

The fire demon nods his acknowledgment as Kurama retreats to make his tincture or tea, still breathing through the way his stomach rolls and pinches, trying to make him give in to vomiting. He is stubborn as always, long breaths of cold night air sustaining him from giving in until Kurama returns. There is no point in bickering with him that he does not have time to begin with, not to mention not having time to be ill like this. Kurama would never see eye to eye with him on this, and more than likely would see right through it as an excuse he is making in order to try and avoid all of his turmoil over the two of them.

Kurama will find him pacing, arms crossed behind his head when he returns, still breathing in a slow, measured pace, muttering to himself about about how stupid all of this is.
