In order to have a bright future, her biological mother made a mistake and abandoned her.
For the sake of bloodline dignity, her adoptive mother poisoned her to death.
Before her rebirth, she was a gentle person. Even if it was difficult, she would never let go and be warm and happy.
After her rebirth, she lived tenaciously, knowing that only by becoming a master could she crush all her previous grievances and lows.
From now on, the joy and sadness are as cold as water, but I still wish to spend the golden years with you.
