This story is so hard to follow. And reading all the revelations about blood ties makes it even more messy. Taeha may have breathed fire and ice, he may have been ruthless and cruel to Hawon, you can still guess that his feelings are genuine and that he cares a lot, whereas I can hardly feel anything from Hawon's part. If anything, he is still very uncomfortable around Taeha, if not scared by him. Not that I blame him, though.
