This definitely will need "supernatural" tag in future.
No matter how I look at it ..
Kwon definitely not 100% human.
Especially story about that festival they are going to celebrate at the village seems implying that:
Kwon is either a full dragon that transformed (maybe when he met his mom, he was newborn dragon, and then assumed himself to be human).
Or, his mom got together with a dragon who disguised himself as human.
That explains why Kwon's father was not present, but the mom seems not resent the father?
