My impression of this fiction is that the title is very appropriate. It seems to me that both brother's are talking to a brick wall. Both are stubborn. One brother is telling about his feelings (aka Wataru) on what he is. The other brother is telling about the reality of Fangire politics (aka Taiga). Whether Wataru like it or not, it seems to me the rest of Fangire society will view him as a Fangire because he is from the royal line. Thus, will expect Taiga to not play favouritism.
