Su Chenxi has only two wishes in her life. The first is to take her father's violin to the world. The second is to raise her sister well. The first wish is that she is about to realize the second wish. It is a bit difficult because there is a soul in her sister's body who doesn't know where it came from. A soul said: "If you don't do what I say, your sister will die." Su Chenxi: "What do you want me to do?"
A certain soul: "Can you buy me a can of yogurt first?"
Su Chenxi: "...???"
Then one day after she finished a certain task for a certain soul, she discovered that she seemed not to be a human being? ? ?
