New comer Rainky Wai Yu Sum recently worked on the film LONELY FIFTEEN (LAN MUI JAI)'s continuation WHAT'S UP, GIRL (MEI GAU SIU NUI), reports TVB News World.Because she is normally full of expressions and of her outstanding figure, she caught director Philip Yung Chi Kwong's eyes and had to play a character who had to sacrifice herself.Speaking of playing a lead in her first film, she was both happy and nervous. "I am afraid of being inexperience, especially with the bed scene! (Have you made any preparation?) I had to lose weight so I would look better on camera, and I had more facial! I even watched many movies with similar subjects for research." View pictures of Rainky and other Asian celebrities who changed their appearance over time.
