After My Beloved Junior Brother Was Possessed by My Archenemy

A cold, wooden heroine x a flashy peacock of a male lead

Han Su lost her entire family to the demons when she was young. After joining an immortal sect, she vowed to eradicate every demon under heaven.

The day she forced the Demon Lord Jiang Qing to his death with ten thousand swords, Han Su avenged her family. When she returned to the sect, her elders arranged for her to marry her junior brother.

Her junior brother was gentle to everyone and devoted to Han Su. They had known each other since childhood, were childhood sweethearts who loved each other, and were also the sect elders' most accomplished disciples. It was the perfect match.

Han Su thought it was time she had a new family, too, so she accepted the elders' suggestion without a second thought.

On her wedding night, Han Su hid her face behind a fan and lowered her eyes to watch the approaching footsteps. For once, she felt a trace of nervousness and uncertainty. But the moment the fan moved aside, a cool yet gentle voice rang out with a smile: "So this is your type?"

Han Su's pupils contracted. She looked up in disbelief. The face was unmistakably her junior brother's, but the smile in his eyes was now wicked and unrestrained. Who else could it be but the Demon Lord Jiang Qing?

Their wedding night ended in disaster. Han Su hated him, yet there was nothing she could do about him.

One day, when Jiang Qing once again put himself in danger while using her junior brother's body, Han Su could no longer hold back and thrust her sword at him. To her surprise, he stopped it effortlessly between two fingers. The sword tip halted before his chest.

Jiang Qing looked at the sword, smiled, and said, "Senior Sister, are you flirting with me?"

Han Su furrowed her brows, anger on her face. He was certain she wouldn't do anything to him. With her junior brother's abilities, she could kill him using only seventy percent of her strength, but she hadn't.

The man before her smiled, utterly unafraid. "Senior Sister, don't do that next time. What if I can't catch your sword next time? Your beloved junior brother might have to be reborn."

Han Su gritted her teeth. "Don't call me Senior Sister!"

Jiang Qing had been a carefree demon. Somehow, he had offended Yuan Hansu, who insisted on killing him. Eventually, she really did kill him, and his body was destroyed. He was reborn in the body of her beloved junior brother.

When he used this body to take risks, he upset Han Su, but he didn't care. Han Su often let her gaze linger on him, caught between love and hate, and he found it amusing.

But later, whenever he put himself in danger and she rushed to save him, he found his own gaze lingering on her for a long time. He could no longer tell whether she was saving him or her junior brother. Later still, he suddenly began to hate the face he was wearing.
