[Two female leads. If that's not your thing, please don't read.]
Lu Chumo was an orphan from childhood. After growing up, she worked three jobs a day to pay for the orphanage director's surgery, but died suddenly from overwork.
After death, she was suddenly bound to a salvation System.
The System told her that completing missions would let her return to the real world, and she would also receive a billion in cash as a reward.
Lu Chumo swallowed the refusal on the tip of her tongue. What was she waiting for? She'd better get those missions done!
One: The real heiress forced to marry into a wealthy family in someone else's place
Two: Her uncle's autistic girlfriend
Three: The empress trapped in the imperial palace
Four: The CEO's stand-in second female lead
Five: An unloved princess forced into a political marriage with a neighboring kingdom
More worlds to come...
