A very stubborn girl. People give her advice, but she never takes it even though they may actually be right. She has to learn everything the hard way, when something actually happens to her. She likes younger guys. Some day, she'll be a Cougar. Also, a very violent person. If you say anything relatively bad to her, she'll slap or Five-Star you.
Kevin said that she shouldn't be dating Horace because it was the wrong thing to do, so Jie-En slapped Kevin.
