Susan has been a little depressed recently.
Because she found herself in a three-travel world of book travel + quick travel + time travel,
It seems to be an Otome female sidekick setting.
The original owner had many brothers, all of whom were extremely good-looking and none of them were biological.
The system said that you have to kill the heroine and conquer them one by one, which made Susan feel very depressed.
On the way to the strategy, Susan discovered the deep malice coming from the system. How could there be so many hidden characters? Did the father of the original owner have a habit of adopting sons? Hey!
So my brothers noticed that our sister always seemed depressed recently.
