"Since my elder sister has entered the palace, my younger sister is willing to accompany you." As you are friends, she is happy to accompany you.
"This palace is deep, I only want to protect my sister, and she will be safe in this life." She tried her best to protect her.
"I only want to be with my sister forever." She persisted in this for the rest of her life.
"Sister, I'm sorry, sister can no longer protect you." She died tragically, and she was heartbroken.
"I can't die, I want to avenge her." She planned carefully and took every step to get her revenge.
"Sister, if there is an afterlife, we will meet again..."
"If there is an afterlife..."
Purpose: Love without fear of life or death
