KEY TO HAPPINESS:(My mute devil) - Chapter 75

​The world, Earth, was devastated by the Great Incursion, an apocalyptic invasion by dimension-hopping monsters. Humanity's only hope now lies in Galaxy Fall, a newly accessible parallel world where they can gain strength through a System of quests and missions.​Five hours after the Invasion, the betrayed survivor Mirabella is mysteriously reborn and gains a unique power: the [Master Account System].Her initial skill is the deceptively simple but devastating 'Multiplier x100', which applies a 100 times buff to all her offensive capabilities, including physical attacks, spirit energy skills, and damage-over-time effects.​Mirabella must now transform from a silent survivor into the world's most feared warrior, who was only scared of one thing, which is?“I Hope I don't run out of opponents in Both worlds.”

She was stupidly in love with him. Because of him, she became rude and unreasonable, overbearing, jealous, insane. But he did not spare a glance to her. Married for two years, he didn’t favor her once, letting her become the laughing stock of the whole world. Eventually, she ended up in an affair, leading to her tragic death.

The Swordmaster who has returned by chance to save the world!

Su Yanyi: The president of Resplendent Entertainment, the legendary Entertainment Queen, and the support pillar every artist wanted.

She lost everything to one scheme, and only then did she realize that the man she had always treated with coldness and indifference was actually deeply in love with her. At the end of her life, she was left with endless, irreparable regret.

“If I am given another life, I will make every single person who owed me pay me back a hundredfold, and I will do everything within my power to ensure you a safe and happy life!”

Maybe her persistence was simply too impressive, because in the blink of an eye, she returned to a time three years ago and obtained a very special System—The Virtuous Wife System.

Was this telling her that she had been the Entertainment Queen for too long, so she should try something new and become a virtuous wife instead?

Qin Jiran: The new generation Film Emperor, handsome and domineering, a lofty male god in the eyes of countless fans.

In his entire life, he only ever loved Su Yanyi. It was a pity that she did not love him back, and even after three years of marriage together, it was all still just a contractual transaction to her.

“Yanyi, do we have to divorce?” Hidden within the man’s cold, hard expression was deep sorrow and despair.

In both her past life and her present life, their fates intertwined. Su Yanyi was reborn back to the day they were supposed to divorce.

Will she adhere to the choice she had made in her past life, or will she embark on a different path?

With the help of the Virtuous Wife System, the dense and stoic Su Yanyi set out to pamper her oblivious husband, stumbling over her own inexperience as she tried to convince him that no, he was not having auditory hallucinations, and no, she was not feeling ill!

Just, why was the first task —make him smile genuinely ten times— already so difficult?
