Make a promise.

Mrs Luo wasn't in a good mood either with the sight before her. Wang Yong and an unknown girl stood hand in hand with their heads lowered. She had seen Qin Zexi running down the hall crying and she had tried to find out what happened but she refused to say anything so she investigated the matter on her own. She was furious when she heard the full story.

"Who is she?" Mrs Luo asked Wang Yong who was clearly not interested with what was going on. 

Cao Ruomei's eyes narrowed in annoyance when she heard her question but she restrained herself and waited for Wang Yong to respond, her hand unconsciously gripping his own.

"She is my sister." Wang Yong rolled his eyes when he saw Mrs Luo's glare, knowing very well that she knew that he was an only child. "She lived with me and my grandmother when she was alive."

"I see." Mrs Luo's expression relaxed for a minute but she said. "Then what is she doing here during school lessions? Why are you not in class?"
