Teach You to Beat Someone up

"If you ask me, you are too nice to him." Shen Hanxing leaned against the sofa in the bar. Her face was flushed with a hint of drunkenness. "If I were you, I would have beaten Zhuang Li so badly and made him apologize on the spot!"

"Yes. I was too nice and couldn't bear to do it." Wei Xi'er agreed and nodded her head vigorously. She looked around and lowered her voice as she leaned over. She said softly, "Let me tell you, but please don't tell anyone. I slapped Zhuang Li today and I learned that from you... Hehe. I remember seeing how you hit someone. It seemed very satisfying. Sure enough, it was very satisfying." Seeing Zhuang Li in pain, she didn't feel so bad anymore. After all, it was Zhuang Li who cheated. She was the victim. Why was she in so much pain while Zhuang Li was being fine?
