Ahhh this is indeed beautiful!!
The land is governed by 5 kings. Red, blue, green, purple and black king.
Our uke is substituting for his sister, he didn't want her to be a concubine. They seek his sister because she's a star seer with powerful power..
Blue king looks cold, but he seems deep.
Red king is so mellow, he governs his country peacefully. I freaking ship them together. T T
