After dying, Su Tang woke up as the heroine of an angsty novel.
The System told her she had to fill her heartbreak meter to complete the mission.
Su Tang figured, if someone had to suffer, why not make it someone else?
So in the first world, Su Tang was supposed to give the male lead resources and connections, only for him to accuse her of taking advantage of him and seeking revenge. She was meant to die a miserable death, but instead she signed a contract with the down-and-out male lead.
“You're only his substitute. Put away those feelings you shouldn't have.”
“As a substitute, you need to know your place.”
“He's back. You can leave now.”
Su Tang turned a redemptive angst story into a substitute-themed angst story and delivered every domineering CEO line in the book.
It was still an angst story, but now the male lead was the one getting hurt instead of the heroine.
