After completing her quick transmigration missions exceptionally well, Wen Yuzhi was rewarded by the System with a ten-year vacation.
It was called a vacation, but all sorts of difficult situations kept cropping up. Wen Yuzhi didn't care.
No matter how troublesome, this world was just a drop in the ocean of her long career in quick transmigration. She had no need to entrust her feelings to anyone.
After spending countless worlds with that mindset, Wen Yuzhi thought she had become sufficiently detached, until the young man across from her smiled and held out his hand.
He said, "Have a piece of candy."
Wen Yuzhi instinctively hid the bruises on her arm.

Jiang Song was very good at pretending.
Wen Yuzhi knew that from the start.
She thought he'd keep up the act, being generous and gentle around her, occasionally acting spoiled and needy, repeatedly pushing at the limits she set. But she never expected Jiang Song to drop the act one day.
The young man had a beautiful smile, and he loosened his tie with refined grace. Even as he looped it around her wrist, his touch was gentle.
He bent down and coaxed her in a hoarse voice: "Zhizhi, don't go anywhere. Just stay by my side, okay?
"Don't try to erase me. I only pretend for you."

Only later did Wen Yuzhi realize that she had transmigrated into a book. Jiang Song was the first villainous, unhinged male supporting character to gain independent consciousness.
