"Qin Jing, how many times do I have to tell you, Qin Xue's death has nothing to do with me. Yes, I hated her, but I never killed her."
Qin Huan had indeed thought about killing Qin Xue since Li Yang, the man she loved, was in love with Qin Xue instead. She loved him so much, but what about him?
She had tried so hard to gain his attention, but Li Yang only had eyes for Qin Xue. Qin Huan hated her and felt terribly envious.
Now that Qin Xue had died, Li Yang, instead of being with her, still preferred other women.
"Dare you say you didn't target her because of Li Yang? Have you not even thought about murdering her?
Now that my big sister is dead, you finally got what you wanted. I didn't know before that our mother was the reason for my big sister's mother's death.
If it hadn't been for our mother's affair with our father...
She wouldn't have had depression and wouldn't have committed suicide. Trying to pass it off as an illness-related death was just a lie to deceive my sister.
