After she transmigrates into a book, Yu Chengyin spends the first eighteen years of her life, as a minor character, with everything going smoothly. Her only hardship comes from the second male lead, Li Mu.
Yu Chengyin doesn't regret helping him in his hour of need and making his ambitions come true. She doesn't regret exhausting herself to help him climb to the top.
Her only regret is giving him her heart.
The devoted second male lead is destined to love the heroine with unwavering loyalty.
Yu Chengyin watches helplessly as Li Mu makes the heroine his empress, ends the fighting for her, and builds her a grand pavilion.
At the height of his success, Li Mu is grateful that she never abandoned him and issues an imperial decree making her a consort.
Yu Chengyin laughs.
At least she managed to stop in time.
But Li Mu refuses to let her have her way.
"Li Mu, you have an empire in your grasp and a beauty by your side. Why not let me roam the world and retire in peace?"
"Chengyin, I can't let you go."
Yu Chengyin takes a deep breath and rolls up her sleeves. "If you can't understand it when I put it nicely, fine. Today, I'm taking you down with me, you scumbag!"
After making her bold declaration, she fights with the resolve to perish alongside him. In the struggle, Yu Chengyin loses her footing and falls off a cliff.
As she lies unconscious and freezing, a warm body draws near...
When Yu Chengyin opens her eyes, she meets a pair of clear, dark eyes.
And she's in a wolf's den, surrounded by danger.
The wolf boy sniffs her and watches her, trying to decide which part to eat first.
Yu Chengyin secretly pulls the leather belt from her waist, wondering how to put a collar on him.
According to the Records of Jichuan, in the eighth year of Dingyuan, while farmers were grazing their livestock at the southern foot of Mount Wudu, north of Jichuan County, a pack of wolves suddenly attacked!
As the farmers fought them off, they were startled to see a young boy with his hair in a child's topknot crouched beneath a wolf's belly, glaring and snarling.
The boy was strong and sturdy, his face hidden by his unbound hair, but his clear, dark eyes were bright and striking.
The farmers escaped by sheer luck. Afterward, word of the "wolf boy" spread far and wide.
"Where have you been wandering off to this time? Have you memorized The Expanded Book of Virtue? Come here, I'll test you."
Yu Chengyin beckons to the boy with a finger. He lets out an unwilling growl, then comes over and presses his cheek into her palm.
At a certain point in the story, Yu Chengyin suddenly realizes that the wolf boy is the male lead!
And the male lead is destined to belong to the heroine, too.
Along the way, Yu Chengyin and the wolf boy support one another through thick and thin.
When the boy returns to his rightful place, Yu Chengyin decides it's time for her to leave the story.
On the day she leaves, he rides after her and bites fiercely into the back of her neck.
"Ayin, you know wolves are the most loyal. You can't go anywhere but stay by my side, or else..."
As he speaks, the boy takes out a collar.
Yu Chengyin, finding the collar oddly familiar: "..."
Did she... accidentally "stolen" the man who was supposed to belong to the heroine?
They tame each other, and each becomes the other's most loyal servant.
Note: The male lead has a hidden identity.
