For those who don't know who this character is:
This is the main character from game Swords of Legends 3
Her name is Yun Wuyue, and she's not human, kind of like a fairy
The stage, as long as the dragonfly sign in the background, is her "dreamland" in the game, where she protects herself and stores her memories.

This game is heavily story based, so for those who doesn't speak chinese, i feel bad that you couldn't enjoy the game
