I just remember that it was a long manga and I was impatient and whated to know how it ended. So I looked and downloaded the chinese raws. At that time I was beginning to learn some characters so I didn't know the content of the raws, even if I read the raws now I would only understand 1/8 or 1/10 of the content...

And the art work changes during series.

Esthétique SUM:
Ding Jiayu dreams of being a photographer. Her idol is none other than Yung Jo. When Yung Jo’s photography company holds an audition to find a new photographer, Jiayu decides to take a chance. The thing is, Yung Jo’s company doesn’t hire women, so Jiayu has no choice but to dress up as man and enter. Yung Jo takes great interest in Jiayu's talent and makes her his apprentice. It may seem like a dream to work with your idol, but for Jiayu, it's nothing of the sort. She takes a beating from Yung Jo everyday, and since all the crew members think she is a guy…

sequel sum;
