"Your name is XX. Last night, you witnessed a murder."
"As a suspect, find the real culprit and survive until the end of the game."
"Pay close attention to the molars in the can, the dead fetus in the stone, the ashes in the dry well..."
"Anyway, dear detective, good luck."
Su Mian, an extremely misanthropic and sickly female college student, transmigrates into an infinite flow world.
The system made her play the roles of a mentally challenged child, a yandere doctor, a demonic nun... and she couldn't go against the character settings, because once the character settings collapsed, the instance DM would give her a terrible punishment.
Why does she always encounter the same DM in every game, and why are the punishments different from those of other players?

tips:
1. The female protagonist is a character who grows and develops. She is afraid of the male protagonist in the early stages. Her advantage is her intelligence combined with the male protagonist's combat power.
2. Mutual redemption and mutual submission; the female protagonist suffers from mental illness.
