He said: "Why was it so hard? I thought we're doing it at an angle?"Edwin later said: "I have never been slapped by women before, except for my mother. (Upset?) How could I be upset, just one sorry from Christine and I already feel better."When we were filming, I got slapped about 11 times because of all the NGs. My friend actually envies me for having two beautiful on-screen girlfriends."When Christine was asked why she slapped Edwin so hard, she explained: "I just heard someone said 'action' and my acting just came. I don't know how to fake it and I get very into character."Edwin was standing besides her and joked: "Then it would be great doing kiss scenes with you. Once you get into position, you would just keep on kissing."
