After穿书I Became the Tyrant's Beloved Pet

After staying up late on New Year's Day to finish reading a novel, she dropped dead. When she opened her eyes again, she discovered that she had transmigrated into the book and become a little pink, chubby bird given to the future tyrant.

At first—

Xiao Changqi: It's just a little beast. If it's obedient, I'll raise it. If it's not, the kitchen can add roasted bird meat to dinner.

Yuandan? Little pink ball? Chirp!

You wicked old man, you're so bad!

Later—

The court officials watched the Emperor head to the morning court with a little pink ball on his head, witnessing firsthand what it means to 'wreak havoc on the Emperor's head.'

Just as Yuandan was recklessly abusing her privileged status, one day, she transformed back into a human in the tyrant's embrace.

Yuandan: ...

Xiao Changqi: Yuanyuan, I saw...

Yuandan hastily reached out to cover his eyes: No, you didn't see anything.
