An assistant

Luo Huian glanced at the mer in front of her with a slight annoyance on her face. If this mer had not interrupted then she would have sent that woman to the police station where she was supposed to rot. 

"I never thought that you liked playing the role of saviour," she remarked sarcastically with an expression of derision. If not for the fact that Luo Huian couldn't hurt the mer, she would have said something even harsher. "But then again you have to keep up with the public image?"

However, if she were to make such remarks and hurt others —it would go against her beliefs as well as her mission. 

Wei Yucheng smiled gently at Luo Huian's words. He shook his head and replied, "It would be better to say that I was playing the role of your saviour, Miss Huian."
