I Transmigrated into a Book, and the Demon Lord Wants to Die. What Do I Do?

[Transmigrate into a book + zany, lighthearted, sweet romance + scheming + female side character + villain]

[Lively, goofy cannon-fodder side character + scheming, obsessive villain]

One morning, Jiang Zhitao woke from a dream to discover she had transmigrated into a book, right into the bed of Murong Xuan, a man born with a demonic constitution.

At the worst possible moment, while he was choking her, that lousy System told her she had to protect the great demon. If he died, the world would be plunged into catastrophe, and she would die inside the book, too.

But... this great demon was determined to die!

After witnessing all 365 ways Murong Xuan tried to get himself killed, Jiang Zhitao discovered that the great demon was immortal. Only demonic power could fight poison with poison and destroy him from within.

Still, for all his obsessiveness, the demon was easy to fool.

She tricked him into believing she was a goddess sent by Heaven to save him, and he believed her, but said he didn’t need saving.

Later, however, she looked at him with tears in her eyes and said, “Murong Xuan, I want you to live. You are not allowed to refuse.”

Sitting beneath the moonlight, he somehow found himself nodding.

The great demon, who had been bent on dying, developed the faintest desire to live because of her.

In their brief time together, Jiang Zhitao wanted to tell him more than once: Murong Xuan, stop trying to get yourself killed. Just watch me carve out a path to survival for you.
