The main issue here is the dynamics after all, not the "age gap". Taehyuk raised hyo-un for 10 years, had it been 1 or 2, there wouldnt have been a real problem.
1.On one hand this is somewhat okay because the Dragon isn't really human
2. On the other hand the male lead basicly watched him grow up, raised him and is basically his father figure
