I've only seen the first episode so out loud thinking time:
who is his father and why did it piss off his mother's God (shamans have deities? are they ancestors who guide them? I am ignorant).
he has less yang and she has more yang.
her blood had the spirit runninggg and I wonder if it would have reacted the same to another person.
she's the secret daughter of the king and his father is unknown.
honestly right now their dynamic screams squabbling friends so if they end up being related in some way, I wouldn't mind.
I wouldn't mind the romance either but I've watched them give interviews where the age difference is so obvious (SOMEONE SAVE HIM, HE'S SO UNCLE AND AWKWARD LMAO) and if it stays platonic I would also vibe with that too.
