I can see it, shuraka is a green flag for Tei, but that doesn't he doesn't have some red flag hidden somewhere, can't wait to see his dark side, I mean to take care of an empire and fight for your spot as a crown prince since the age of ten, it requires the person to be merciless in a lot of occasions, probably Tei was his only light and motivation!
Well .. I'm here cause obviously I have no life .. hehe ..
