Only when she was dying did Song Xun learn that the world she lived in was nothing but a book, and that she was merely the vicious supporting female character there to set off the heroine.
Before the heroine appeared, she came from a distinguished family, excelled at school, and was widely recognized as the campus beauty. But after the heroine showed up, it was as if her intelligence had been nerfed: she kept framing the heroine.
In the end, a group of the heroine's followers joined forces to attack the Song Group, driving it into bankruptcy and saddling it with enormous debts. Song Xun was injected with a massive dose of drugs, then thrown into the sea, where she ended up in a shark's belly.
After being reborn, Song Xun decided that even if she was the villainess, she could still be a gentle blade, striking with every blow.
To everyone who ever hurt me: are you ready? The game is beginning!
