"This is just an effect depicted in movies. When it really comes down to it, it's all about the face," Zheng Yichen said, sharing his thoughts. "Think about it, if you were an ordinary person and a beautiful, capable witch took a liking to you, there'd basically be no reason to refuse..."
In fact, anyone with a relatively normal mind would hardly refuse and wouldn't really have the ability to do so either. But that's the movies for you. If no one refused, if a beautiful witch came knocking and you simply nodded and agreed, then what's the point of making a movie?
Err, it's not that the story couldn't continue. It would simply mean that after the witch declares, 'I've come to join you,' a new enemy who hunts witches would emerge, and the male lead would struggle side by side with the witch to fight off this witch hunter.
Either the hunter gets defeated in the end, or the witch hunter gets convinced and turns a blind eye, just letting the matter slide.
