After Transmigrating into a Book, I Was Entangled by the Yandere Villain

Yu Wenxue transmigrated into a side character in a romance novel, completely unrelated to the original plot. She was unexpectedly bound to a kissing system that required her to facilitate the protagonists' romantic progress and observe their kisses periodically, lest she face punishment. This meant becoming a voyeur!

To survive, she complied, but the tasks were fraught with difficulties. Task one involved the male lead accepting a sachet from another girl. Task two saw the female lead manipulated into a compromising situation with a male supporting character. Yu Wenxue felt exhausted!

She diligently completed each mission. However, every time she surreptitiously watched, she felt another pair of eyes on her – those of Gu Yunshen, the book's biggest villain. The novel described him as handsome and beloved by many women, but also as the male lead's half-brother, who, after a childhood trauma that caused hearing loss, blamed his brother and actively obstructed the protagonists' romance.

To prevent Gu Yunshen from further sabotaging the couple's love story, Yu Wenxue was given an additional mission: to stop him from turning to villainy. She frequently appeared before him, intercepting his every move. For instance, she held his hand when he intended to poison the male lead and clung to his waist when he drew his sword to kill him.

Finally, during her third attempt to stop him from committing murder, Gu Yunshen blocked her path, his eyes fixed on her, asking, "How will you stop me this time?"

As the original novel's protagonists celebrated their wedding night and the villain matured into an upright young man, Yu Wenxue believed her mission was accomplished. As she packed to go home, the system's cold prompt echoed: [Host must complete the hidden mission: kiss someone three times. The target is your choice.]

Before she could choose, Gu Yunshen cornered her, kissing her forcefully and repeatedly. His deep gaze held a chilling intensity as he asked, "You wanted to kiss someone, didn't you? Why didn't you come to me?" Yu Wenxue looked down at the chains on her feet, realizing his obedient facade was merely a disguise.

In the beginning, Gu Yunshen had a poor impression of the girl secretly watching his brother. He played along, attempting to expose her supposed hypocrisy. But she was as timid as a rabbit, her eyes reddening with the slightest scare, which he found uninteresting.

Later, when he fell into disgrace and was scorned by all, it was she who rescued him from the darkness. He knew his methods were despicable, but he wouldn't let her leave.

The following is the blurb for the pre-sale novel "The White Moonlight of the World-Destroying Demon Has Returned" — Yuan Ciyue, who suffers from social anxiety and has slow reactions, was accidentally chosen to攻略 (charm/win over) the world-destroying demon to prevent him from destroying the world in the future. The world-destroying demon was rumored to be exceptionally handsome but cruel and a notorious killer. Indeed, upon arrival, she witnessed the 98th strategist being carried out covered in blood.

As the 99th strategist, Yuan Ciyue, pale-faced, abandoned the strategy mission and fled. To deceive the system, she turned her attention to a handsome young man she had rescued. He was covered in wounds, with only his face presentable. She proposed they pretend to be married and she would take him in to recover, while he would help her overcome difficulties.

The young man was highly skilled and gentle. He protected her and took meticulous care of her daily needs. In the cold winter, he would warm the bed before letting her in; in the hot summer, he would fan her and help her fall asleep. Over time, Yuan Ciyue felt that life was good.

On their wedding day, she heard the system prompt that had been silent for a long time: [Congratulations to the host, the strategy mission is successful!] Yuan Ciyue looked at Chi Yanzhou, who was applying makeup for her, with confusion. How could such a gentle and considerate husband be the violent and tyrannical world-destroying demon? He was clearly... so good.

Facing enemies on all sides and betrayal from loved ones, Chi Yanzhou lay bleeding in the mud. In his most desperate moment, Yuan Ciyue appeared, rescuing him from the abyss, only to disappear suddenly, cruelly trampling on his heartfelt sincerity. She vanished, and he frantically searched the three realms but could find no trace of her. It turned out she was a strategist, and her actions were merely to guide him toward goodness, making him a deity on the altar.

After killing the so-called strategist for the 98th time, she appeared. He knew she was soft-hearted, so he deliberately injured himself and appeared before her. As expected, she saved him. On their wedding night, Chi Yanzhou, extraordinarily beautiful with his dark hair cascading down, looked at Yuan Ciyue with infatuated eyes, as if gazing at the moon. His fingertips lightly touched her face. "I've waited a long time for you." Even if he had to shatter the laws of heaven, he would defy causality to find her and cling to her.

The day the world would be destroyed eventually arrived. Yuan Ciyue was forced to leave this world, and as the system took her away, the only passage back was closed. Wailing and bloodshed surrounded her. She watched nervously as Chi Yanzhou approached. So he really was the demon...

Just as she prepared for the worst, she saw Chi Yanzhou wade through mountains of corpses and rivers of blood, kill the system that was issuing orders, lean down, and kiss her forehead. His voice was low and possessive, "Yuan Ciyue, can you see this through to the end this time?"
