Twenty years ago...
Chen Rui's mother died in an accident together with her younger sister who was still a baby. Not long, her father, Chen Luizhi remarried after his wife passed away.
Her new mother, Tang Xue, and her daughter, Tang Yurou may have acted kind whenever they were in Chen Luizhi's presence but whenever he was not at home, they would usually abuse her.
Later on, when Chen Rui reached high school, she found out the truth about her mother's death by overhearing Tang Xue's conversation.
"Yes, I'll keep in touch." Tang Xue said on her phone. "I'll take care of the child she left. I'll remove her out of the picture and bring you here."
Chen Rui was hiding behind a tree. They were currently in the garden. She followed Tang Xue when she saw her acting strangely.
"Killing that bitch was easy so how much more her child? If she didn't saw me with her husband, she could have lived a few more days."
