"It's different," he said, "but it looks good." Did he prefer her natural color? Yes. But she didn't look bad, and he wasn't going to insult his girlfriend. That would definitely be bad form. And he definitely wasn't going to complain that said girlfriend wanted to stay in and spend time together. It had been hard, convincing Chris to give this a shot, but it really did seem like she was giving him an honest chance and that meant a lot.

Meet a nice girl, who was apparently his guardian angel, like the girl and start dating her...find out the girl was replaced by someone evil. It really was just his luck.
