Blurb One:
Once, she was the younger sister he cherished with all his heart.
Later, she was his sworn enemy, locked in a battle to the death.
In the end, she became the love of his life, whom he would love beyond death.
He hated her, and loved her. He wanted her dead, yet wanted her to live.
Why did he only understand this after she died?
Fortunately, Heaven gave him another chance to choose.
This time, he wanted nothing else. He wanted only her.
Beautiful, bold, clear-headed, and resilient heroine X deranged, obsessive, love-addled hero
The hero is genuinely insane early on, with a dual personality (inner demon/older brother).
Plot-focused blurb:
The old Xu Liangyue was exceptionally gifted, a Demon Clan princess whose name struck terror into people's hearts.
After her resurrection, Xu Liangyue has a heart of wood, mediocre talent, and no cultivation left. Like a tiger fallen into a plain, she becomes a puppet belonging to her sworn enemy, Ye Xuechen.
The old Ye Xuechen was the most outstanding disciple of an immortal sect, refined and noble, treating her with a face as cold as frost and a heart as cool as the moon.
Now, he has fallen from immortality into demonic ways, breathing his soul back into her through a kiss and feeding her his blood essence, begging her to come back to life.
No one knows that Xu Liangyue was once Ye Xuechen's younger sister, born of both human and demon blood. Their parents died protecting her in the war between immortals and demons, and she was left to fend for herself among the demons while still young.
When they met again, she was overjoyed. He already hated the Demon Clan to the core.
She never got the chance to tell him she was his sister.
She never expected Ye Xuechen to fall for her false identity at Minghua Sect. He hated being deceived by the demons, and even wounded her badly with a single sword strike.
A chasm lay between them that she could not cross even at the cost of her life. She thought they could speak only of interests, never of feelings.
But when she truly died because of him, the world did not unfold as she had expected.
Her former close friend among the demons wanted her dead, while her old nemesis from the immortal sect was willing to die for her.
When she returns from the end of the road to the moment the clouds begin to part, right and wrong, black and white, love and hate may never have been so easy to distinguish...
Blurb Three:
What does this man want from her?
He's the one who obsessively turns her into a puppet, consumed by madness.
He's also the one who calls her his younger sister, restrained and rational.
His heart is split in two. One half craves absolute possession, enough to destroy everything; the other chooses patient protection and letting go.
Even he doesn't believe she could love him.
How could she love him?
He said it himself: no matter how different the two halves of his heart may seem, no matter how much they deny it,
they are still one person.
He is a monster, mad to his core.
She would never like him.
She only treats him as a weapon and a servant.
This weapon is so useful that she can't bear to let it go.
But why, by the time they reach the end of this journey, does she still...
P.S.:
The heroine was adopted by the hero's parents. They are not blood-related.
