The Transmigrated Alpha Who Only Obeyed Him

Xie Yuheng awakens inside an ABO novel as the infamous villain his sister once despised. But unlike the original villain, this Xie Yuheng is a brilliant, gentle Alpha with ocean-blue eyes, a fragile heart, and a body that betrays him at every turn.
Then he meets Gu Zhaoyan-the cold Omega who remembers everything.
In his previous life, Zhaoyan was destroyed by the villain, betrayed by the protagonist, and eventually became powerful enough to crush them both. Now, he watches the changed villain with suspicion.
Yet suspicion becomes curiosity, curiosity becomes possessiveness, and eventually, love.
But Zhaoyan discovers Yuheng's secret: he doesn't belong to this world.
