Why Is the Villain Getting Crazier After I Transmigrated Into a Book?

[Transmigrate into a book + historical setting + no golden finger + devoted couple + happy ending]

A resilient, easygoing, kind-hearted heroine vs. a Villain who starts out normal and turns into a crazed obsessive

Gu Zhijin wakes up one day to find she's transmigrated into a book, where she gets entangled with the Villain. After several encounters, she thinks the book's description must be wrong: Lu Yu is clearly a wonderful person.

Only after marrying Lu Yu does she realize that he's no good man at all. He's a ruthless wolf who keeps his claws sheathed when facing prey that interests him.

Gu Zhijin sighs. How do you get off a ship once you've boarded it?

“Leave? Where would you go, Zhijin? Why not take your husband with you?”

“Of course, of course! I'll definitely go with you.”

Gu Zhijin thinks that if she can't sever their ties, then she might as well walk alongside him. She hopes he'll be safe and that everything will go smoothly for him.

“Husband, look how beautiful the world is! So don't grow weary of life, okay?”

Before long, Lu Yu ascends the throne and invites her to sit beside him. “It really is beautiful. Come here, Zhijin.”

Since his wife loves a peaceful and prosperous age, he'll give her one.

Gu Zhijin...

That's not what I meant!

What do you do when your husband is this powerful?

Gu Zhijin says she can only spoil him herself.
