In her previous life, she truly hadn't planned to kill Xiao Bao, to harm her aunt, but her aunt was too biased, so she... she harbored deep resentment towards her aunt.
Later, when she learned that her aunt intended to leave all the inheritance to Xiao Bao, she became so jealous that she lost her mind and conspired with Fan Lei to kill Xiao Bao.
After Xiao Bao died, she was afraid her aunt would discover something, so she went all the way and poisoned her aunt.
It wasn't until she squandered all her aunt's property and then contracted a terminal illness, with no money for treatment, that she began to feel some regret.
But she didn't regret harming her aunt and Xiao Bao; she regretted giving so much money to Fan Lei, allowing him to squander it all in just a few years.
