This was part of the bloopers for Romantic Princess. Here you can somewhat see Wu Chun's tattoo on his arm. The dude in the back is the director of Romantic Princess...hehe...he's trying to be muscular like Wu Chun.
This is also part of the bloopers...Wu Chun is acting silly here.
Now this is in the series. Here, the fake granddaughter is daydreaming about what Wu Chun might do to her tonight. Ooo ~la ~la
The fake granddaughter looks really scared and Wu Chun is about to take off his bathrobe here.
