Well about the moment when Shuraka said "How exhausting...," I don’t think it was directed at Tei, considering Shuraka's devotion to him. It felt more like he was exhausted by the whole situation - the circumstances he was born into, his beloved not fully understanding him, his own inability to reassure his loved one. All of that together probably made him say that. As far as I've come to know Shuraka from a reader's perspective, that man isn’t capable of saying a single negative word about Tei. I just hope the next chapters don’t prove me wrong. I will keep believing in BWAT!
