Dont remember

"Ivy An, girl, how you disappeared on all of us? You know Amanda has been asking about you but no one knows where you are. You changed your number," The boy said as he continued to stare at her. He didn't seem happy as he went on saying, "Why aren't you talking? Are you still mad? I'm sorry. I didn't tell you before that I and Amanda were dating. You know it was not easy for us to hide this from you after all she is your best friend."

According to his words, that Amanda girl and she were best friends but why didn't she remember about her so-called best friend. 

"Ivy…" When the boy felt that there was something wrong with the girl, he moved ahead to shake her but before he could touch her, he felt someone pushing him away. 

"Who the fuck are you!" A fierce teenager pushed him away as he pulled his stiffened sister to his side. As she was in Lu Xuan's arms, her entire body began shivering. She could finally react as she felt that she was safe.
