Suicide?

Lisa sat in a dark room, staring at nothing in particular. Her mind was occupied with a whole lot of things and it was messing her head up. 

Firstly, she had seen a picture of her father laughing together with Mrs Hwang, then, another picture where Mrs Hwang had been standing with Mrs Park, and another where Mrs Park was seen together with Zhu Hansong who was allegedly her sister's boyfriend in the past.

Now the question is.... how were they all related? How did they all come to the event her sister had hosted? Did Zoe have anything to do with both women? Or had they gone there because they were her father's friends? Or probably mother's friends? And how come Zhu Hansong was seen together with Mrs Park?

She suddenly paused when she remembered something. Zhu Hansong had come with Amanda to the party the Hwangs had held.

It meant Zhu Hansong and the Parks had gone a really long way back.
