She Was Evil Spirit

"Oh, madam, I'm sorry."

"That one was your sister, wasn't it?" The old woman smiled kindly as she asked, making it impossible for Li Si An to ignore her.

"Ah, yes, madam. He is my younger brother, Li Junxu. Em… how about you, your grandson must be one of Junxu's friends?"

"I have a granddaughter."

The woman answered then stopped talking. She didn't seem very interested in discussing anything about her own granddaughter. It's strange, usually parents are very enthusiastic.

"I might be wrong about something… you don't seem like an evil spirit." The old woman admitted in a low voice. "I can feel it after watching you throughout the show."

What did he say? Evil spirit? Who?

"Sorry madam, you think... I'm a bad woman?" It somewhat hurt Li Si An's heart in a strange way. Li Si An is not evil, she greets and behaves politely to the woman. Why is she called evil?
