On this episode, Yona witnesses her father being murdered by Soo-won. Later, Son rescues her and they escape the palace.
So on the first episode, it was kinda typical until the second episode where they revealed much better details. It's like Robin Hood meets one of those Chinese/Korean kingdom movies. Anyway, the action was decent along with the main plot build up. I really can't wait to see what happens next. Overall, nice build up and action.
Conclusion: Nice build up and action.
